API(Pabbly) not connecting giving error

Hello,

Thank you for reaching out to Pabbly Support.

The error "One or more validation errors occurred: Value cannot be null" happens because cloned workflows copy the structure of the steps but do not automatically transfer the live captured response data from the original workflow. As a result, the parameters mapped inside your API by the Pabbly step are receiving empty/null values, resulting in a 400 Bad Request error.

To resolve this, please follow these steps:

1. Open the Cloned Workflow and go to the Trigger step (Step 1).

2. Click on Re-capture Response.

3. Perform a test action in your trigger app (e.g., submit a test form or create a test record) so that Pabbly Connect receives fresh sample data.

4. Go to your API by Pabbly step (and any intermediate steps), ensure the required fields/JSON payload are properly mapped with the newly captured data, and click Save & Send Test Request.

5. Once the test request is successful, make sure the workflow is turned ON.

Please give this a try and let us know if you run into any further issues!

I have done the mentioned step but same error i am getting .. check json data is changed but getting error

Hello,

Thank you for confirming that you have recaptured the response and updated the JSON data.

To investigate the API by Pabbly validation error further, could you please share the API endpoint URL and the API documentation/request format provided by the application or service you are connecting to?

The current response shows validation errors from the API, including the requirement for a lead field. To determine the exact JSON structure expected by the API, we need to verify its required request format.

If possible, please share:

• API endpoint URL

• API documentation/sample request JSON

• A sample of the request format that works successfully outside Pabbly, if available

Once we have these details, we can review the JSON structure in your cloned workflow and guide you with the correct configuration.
