Cannot Access JSON Body Field in “API by Pabbly” Module Even After Correct Settings

[Anamitra]

Hi Pabbly Team,

I’m encountering a critical issue while setting up an integration using the “API by Pabbly” module.

---

What I'm Trying to Achieve:​

We’re setting up a workflow where we:

• Capture a payment webhook from Razorpay
• Map the amount to Silver, Gold, or Diamond tiers
• Send a raw JSON POST request to Facebook’s Conversions API (CAPI)
  This is required to pass fields like content_name, event_id, and user_data for accurate conversion tracking.

---

Here’s what I’ve configured correctly:​

• Module: API by Pabbly
• Action Event: POST
• Payload Type: JSON
• Authentication: No Auth
• All checkboxes turned OFF:
  • Add Headers
  • Set Parameters
  • Simple Response
• Tried:
  • Creating this step inside and outside a Router
  • Saving after each change
  • Refreshing the browser
  • Testing in multiple browsers and incognito windows
  • Rebuilding the API step from scratch

---

The problem:​

Even after all these steps, the expected “Request Body (JSON)” field does not appear, so I cannot paste the raw JSON payload required for the CAPI integration.

This is blocking us from completing the most critical step — sending a raw JSON purchase event with tier-specific data like content_name to Meta.

---

Workflow name is Razorpay to META CAPI​

---

Suggested Fix:​

Please investigate if there's a bug in how the API by Pabbly module renders the raw JSON field under these conditions — especially inside Router branches or due to internal caching.

---

Request:​

Could you please:

• Confirm if this is a known bug or limitation
• Suggest any workaround
• Or enable the raw JSON body input for us manually (if possible)

Looking forward to your help!

Warm regards,
Anamitra

Hello @Anamitra,

You can simply change the Action Event Method to "Custom Request". Once selected, a field named "Data" will appear, where you can map your request body in JSON format.

I hope this helps.
