How to Pass Through Data for API Request using Webhooks Zap App

 

Contribution by Troy Tessalone

Premier Certified Zapier Expert at Automation Ace.

 

Goal

You want to configure a Zap step to pass through all of the data from a previous Zap step via an API request without having to map all of the data points.

 

Zap App

Webhooks by Zapier: Used to make custom API requests.

 

OPTIONS

  • Webhooks - GET
  • Webhooks - POST / PUT
  • Webhooks - Custom Request

 

OPTION: Webhooks - GET

Section: Query String Params

NOTE: These params will be URL-encoded and appended to the URL when making the request. Note: If you specify nothing for this field, we will automatically encode and include every field from the previous step in the query string.

Click the underlined field label to see a tooltip with more info.

 

OPTION: Webhooks - POST / PUT

Section: Data

NOTE: These are key-value pairs that will form the data portion of the request. If you leave these empty, all fields from the previous step will be used.

Click the underlined field label to see a tooltip with more info.

 

OPTION: Webhooks - Custom Request

Field: Data Pass-Through?

NOTE: If true/yes, request data below will be overridden with the raw data from the previous step (you are still responsible for headers thought, like Content-Type).

Thank you so much for posting this, ​@Troy Tessalone! It’s going to be so useful for folks wanting to send everything through without having to map all the individual fields from a previous step! 🧡

When I follow this documentation, to perform a POST webhook request from data within the previous step, I get errors that the data is missing. No matter how I format the data or even if I had this in manually via the field mapping I still end up with this problem

Probably best to post your own topic and include screenshots showing how your Zap step is configured along with any encountered errors.
