Hi everyone,

I’m trying to trigger a phone call in Bland AI via Zapier and pass custom metadata variables into my Blend Pathway (e.g. lead name, company, budget, etc.).

Here’s exactly what I’m doing:

- In the "Send Phone Call in Bland AI" Zapier action, I’m filling the **Metadata field (bottom one)** with this raw JSON:

{
  "leadFullName": "XXX",
  "company": "XXX",
  "typeOfService": "XXX",
  "industry": "XXX",
  "geography": "XXX",
  "searchDescription": "XXX",
  "budgetRange": "XXX",
  "listOfQuestionsAndPointsToClarify": "XXX"
}

- The field above Metadata is left completely empty.
- I’m **not** using “Extract Call Info into Variables” in the Blend Pathway.
- In my Bland prompt, I reference the variables like `eleadFullName]`, `kcompany]`, `NsearchDescription]`, etc.

However, during the test calls, Blend does not resolve the variables — the bot literally says “Hi leadFullName]” instead of inserting the actual value.

Is there a known issue with metadata being passed via Zapier to Bland?  
Do I need to format the field differently or configure something else in the Zap?

Thanks so much in advance for your help!
 

Hi ​@Xavier from Lexa 

For us to have true context, post screenshots showing how your Zap step is configured in EDIT mode with the field mappings visible in the CONFIGURE tab.

Hey ​@Xavier from Lexa 👋

Not sure if you’ve already got this sorted but I noticed the Metadata field’s help text includes this example, which is a bit different to what you’re using:

 

{ "metadata": { "campaign_id": "1234", "source": "web" } }

It looks like your custom fields need to be nested under metadata. Try this JSON instead (replace XXX with the relevant mapped fields):

{ "metadata": {
    "leadFullName": "XXX",
    "company": "XXX",
    "typeOfService": "XXX",
    "industry": "XXX",
    "geography": "XXX",
    "searchDescription": "XXX",
    "budgetRange": "XXX",
    "listOfQuestionsAndPointsToClarify": "XXX"
  } 
}

Let us know how it goes! 🙂

Hi SamB, thanks for your message - I’ve just used a workaround (just using the prompt directly in Zapier)

Thanks!

Thanks for following up here, ​@Xavier from Lexa! I’m so pleased you were able to get it sorted - great work! 🙌

Seems like you’re all set for now, but please do reach back out if you ever need any further help. 

In the meantime, happy Zapping! ⚡️
