About the Developer Discussion forum

Welcome!The Developer area of the Zapier community is a place for dev-to-dev discussion about connecting your API to the Zapier Platform, and integrating Zapier into your product with our Partner API and embed SDK.  Bring your questions as you get started with our developer tools, building and testing your integration.  Share your expertise as a Zapier developer by answering questions and sharing your tips.  While Zapier engineers will certainly be hanging out here and participating in conversations, this forum is driven by community participation.  When you ask questions here be sure to share enough context so that another developer without access to the private details of your account can provide an answer that’s generally applicable to other developers with the same question.  So when should you ask a question here, and when should you contact Zapier support?Great questions for this community: “How can I do ____ with the Zapier developer tools?”  For example, “use my GraphQL API to

Aesthetic record integrations with Square using Zapier

I am attempting to use Zapier to integrate square appointments with my aesthetic record software. It seems as though I can not link that the way I wanted to and I’m coming here as a last resort before I give up. I would like to make it so that if an appointment is made in aesthetic record or square,  the two apps will communicate and  transfer to the other so the time is no longer available. I use AR for my EMR but I hate the scheduling associated with that software. I love the easy of square and the salon suites I am moving to uses them so I was hoping I could integrate the two. The only details I am able to get from AR is if a new customer is entered it will move to square - I figured out how to do that. Or a new invoice but that is after someone is seen and paid. Please let me know if anyone has successfully accomplished what I am hoping to do or if I should just give up because it is not possible. Thanks!

Slack 'New Reaction Added' Trigger Stopped Working for Public Channels After May 7

My Zap using the Slack “New Reaction Added” trigger was working fine before May 7, but it suddenly stopped triggering after that. No changes were made. Can you check what went wrong? There were no changes made to our Slack workspace or account settings during that time. The Zap is still active, and the Slack connection is showing as properly connected in Zapier.Everything was working as expected before May 7, and then it just stopped triggering without any updates or modifications on our side.Could you please check from your end if there were any updates or issues affecting this trigger?

How to use Zapier Formatter to sanitize text for Instagram posts on the free plan

I have a two step zap. On a new Wordpress post, publish to Instagram for BusinessI need to sanitize the text before I publish to Instagram as HTML is included. Does the formatter count as an action, therefore causing my zap to exceed the 1 trigger, 1 action limitation of the free plan?

Troubleshooting Invalid client_id error when integrating Zapier with OAuth2

Hi there,I’m building a platform and want to integrate Zapier with Oauth2 for my users to be able to connect their accounts to be used with Zapier.I’ve gone through the documentation and created a new integration.Everything has gone ok up until this point. When trying to connect with Zapier I’m getting the following:My understanding is that the client_id should come from my platform, correct? So I created a random client_id string that is used both from my platform (and included in the url parameter “client_id=clientIdString”). And the same string is saved in the integrations Application credentials/Client ID. And a followup question to this. When setting up the authentication, step 5, trying to connect to my app, Zeppier does not seem to include the Authentication token in the request header. I would love to get some help with this so I can launch the Zapier integration in my platform.

ShipStation Companion API Access

Hi,I received the attached notice from ShipStation this morning. The notice informs me that with the next billing cycle, I’ll need to upgrade to a plan that includes access to ShipStation’s Companion API endpoints. I have a zap that only connects to ShipStation and as far as I’m aware does not utilize ShipStation’s Companion API. Is this change managed by Zapier and will there be any changes needed on my end?Looking forward to your response!

Is ChatGPT 4o's image generation available in Zapier yet ?

Hi guys ! I’ve seen the launch of GPT 4o’s new API that allows you to generate images via API now, but is it implemented in Zapier yet ? I tried to test it in one of my zaps, but the are absolutely no generated image available in the outputs of my zap. And I really need this new 4o image generation system, not DALL-E… So I was wondering, do I use the right model (gpt 4o-latest) ? Or is the image generation still not available in Zapier ?  Thanks in advance for your answers,Have a good day !

Error Handler Path Not triggered after API Error

Hello community,I’m having a problem with our zap flows. We have a step that makes a POST call to an API and then our flow splits in two. The success and the error paths. Looking at a specific ZAP run I can see that we got a 702 error from the API yet the zap flow continues down the SUCESS path.Is there anything in config that would make this happen?Am I missing something?Thanks.

Creating a Chatbot using Sharepoint for LLM Knowledge

I’ve recently shown an organisation about how AI systems like Claude/ChatGPT can give answers to questions specifically on files that are uploaded into their knowledge base.They’d like me to develop a chatbot that staff could use to ask about HR policies (for example), but they want the bot to use files stored in their Sharepoint to be its knowledge base.Wha’s the simplest way to do this through Zapier?  (Or any tool really!)

MCP webhook integration issue with Claude.ai data population

So I’m using the new MCP tools integration on claudi.ai  I have a supabase edge function that takes in 2 parameters in the payload. If I set those ID’s manually in the tool settings it works , but if I set it to “let ai fill this field” it always posts the request with an empty payload .. ie [ ] .. If I use a zapier code (python) tool claude is able to post the request successfully.  I tried post and custom webhook tools but something seems broken in regards to the zoiper MCP webhook passing data.

Best practices for integrating third-party apps with Logiqly

Hey, I’m Edgar, a 300L University student currently building Logiqly. It’s a Product Analytics & CDP for B2B saas to get insights on how users interact with their apps.Here’s the MVP of the app: --Link removed by moderator--I do not know how the code. My strengths lie in product management and sales/marketing. And I’ve had to be technical enough to understand the approach I’d be taking for my app and just bring onboard back end developers.I’d love a solution that is quick to get a working product out there, while adding more features.My issue?Logiqly needs to allow users connect the tool to other apps they use; Crms, customer support, data collection, cms, marketing, sales etc.What approach is best?1.)

Make (Integromat) sent out this e-mail today:“Starting today, April 3, 2025, we are removing the X (formerly Twitter) app integration from our offering due to X’s API policy requirements and pricing that prevent us from providing a reasonable integration to our customers.

Email alerts for errors

Is it possible to select which email alerts to receive when errors happen in zaps?  For example, we use zaps for Facebook lead ads quite a bit and quite often the email address is not valid triggering an email alert about it. These specific notices happen often enough, it would be really helpful to eliminate them coming in completely versus the notices about other issues like information not sending at all, or an issue with either our CDP or Zapier, etc.

Feasibility of Automating Zap Creation & Authentication via API

We are currently exploring the feasibility of automating Zap creation, including configuring authentication automatically within the Zap. As part of this, we wanted to clarify a few things: Automated Zap Creation: Can regular developers (non-official partners) programmatically create and manage Zaps using the API? If so, what are the prerequisites or limitations? Authentication Automation: Is it possible to automate authentication configuration within a Zap using the API, or does this require manual user input? Are there specific authentication methods that support full automation (Including 3rd party apps)? Partner Access Without a Public App: Can we access the Zapier Partner API and utilize its features without publishing a public app on Zapier? If so, what restrictions or requirements apply? API Limitations: What key limitations exist for the Zapier API in terms of managing Zaps, triggers, actions, and authentication? Are there rate limits or feature restrictions we should con

Schema mismatch issue with hubspot_find_company action in Zapier MCP

I’m integrating with Zapier MCP using the /tools/list endpoint to dynamically fetch action schemas and execute actions. I’ve encountered a blocking issue with the hubspot_find_company action:The schema returned by /tools/list for hubspot_find_company is: json { "type": "object", "properties": { "first_search_property_name": { "type": "string", "description": "First search property name" } }, "required": [ "first_search_property_name" ] } When I invoke the action using this schema (sending { first_search_property_name: "name" }), the MCP backend returns: "Tool call missing required 'name' parameter" What I’ve tried:I confirmed that the schema from /tools/list only lists first_search_property_name as required—there is no mention of a name or first_search_property_value parameter. In the Zapier UI, the action works when I provide both first_search_property_name and first_search_property_value. The backend error suggests that a parameter called name is required, but this is not reflected

Exploring Zapier Functions: Need resources and tutorials

Hey everyone,I've been using Zapier extensively for almost four years now, and I'm really interested in exploring Zapier Functions, especially since I have a background in Python. However, I haven’t been able to find a comprehensive tutorial or official documentation to help get started. I've searched quite a bit but haven’t come across any solid resources or real-world examples of people using Functions. If anyone could point me to a good source or share any helpful material, I’d really appreciate it!

How is the Zapier community integrating AI into their workflows?

Hey everyone! Denis here from ShareAI 👋I’m building ShareAI, a decentralized network that connects idle devices—like your laptop, desktop, or even company servers—to companies that need AI compute power.Think of it like Airbnb, but for underused computers: when you’re not using your machine, someone else can—and you earn from it.I'm really curious how the Zapier community is integrating AI into their automations and workflows. Are you using built-in tools like the ChatGPT or Claude integrations? Are you connecting to custom/self-hosted models through Webhooks or APIs? If you're using open-source models, are you running them locally on your own machine, a small internal server, or are you hosting them in the cloud? How important is cost in choosing your AI provider? And just to go a bit deeper: do you care where your data is stored or whether it's used for training future models? I’d love to learn how the automation community is thinking about performance, privacy, and cost whe
