Webhooks are highly versatile tools that enable automation and provide status updates, making them particularly useful for polling processes. They are fully compatible with platforms like Zapier, Make, and n8n.

​
Adding a Webhook

Currently, webhooks cannot be added via the API. To add one manually through the Captain Data app:
  1. Open one of your Runs and navigate to the Webhooks tab.

Navigate to Webhooks

  1. Click Add Webhook to access a modal with available options.

Add Webhook Modal

  1. Choose one of three event types:
    • Created: Triggered when a job starts and the first task launches.
    • Succeeded: Triggered when a job completes successfully. 
      {
  "uid": "eaab7f39...",
  "job_uid": "b9a260de...",
  "message": "Job successfully finished.",
  "project_uid": "xxxxx...",
  "error": null,
  "recipe_ref": "b9a260de...",
  "workflow_uid": "edcee5c...",
  "workflow_name": "Extract LinkedIn Messages",
  "job_name": "Automated Run"
}
    • Failed: Triggered when a job encounters an error. 
      {
  "uid": "a8e9923c...",
  "job_uid": "88f0a5fb...",
  "message": "Job failed.",
  "project_uid": "xxxxx...",
  "error": "Error while completing action: cannot re-send connection request yet.",
  "recipe_ref": "88f0a5fb...",
  "workflow_uid": "edcee5c...",
  "workflow_name": "Connect LinkedIn Profile",
  "job_name": "Campaign connect with Leads"
}
  2. Once created, your webhook will be ready to use.

Webhook Created

​
Headers Configuration

In the webhook modal, you can configure custom headers for secure and formatted integrations:
  • Header Name: Specify the key (e.g., Authorization, Content-Type).
  • Header Value: Provide the value (e.g., Bearer token, application/json).
These headers ensure proper authentication and data formatting for external tools.

​
Webhook Payload

When triggered, a webhook sends a POST request with the following JSON payload: 
{
  "uid": "The webhook UID",
  "job_uid": "The job UID the webhook has been triggered on.",
  "message": "Default message based on failure or success.",
  "project_uid": "Your project UID. Useful to integrate our API.",
  "error": "If there's an error, this key contains the error message."
}

​
Handling Job Results: Success vs. Failed Inputs

  • Failed Status: Triggered if all inputs fail.
  • Succeeded Status: Triggered if at least one input succeeds, even if others fail.
To investigate discrepancies between inputs and outputs, use the Get a Run’s Inputs API endpoint:

​
Common Reasons for Failed Inputs

  • 404 Errors: The profile or resource is inaccessible.
  • Incorrect Inputs: Invalid or improperly formatted inputs.
  • Authentication Issues: For example, an invalid LinkedIn session cookie.
Example payload for authentication errors: 
{
  "uid": "80149f56-a0e9-4b18-...",
  "job_uid": "92681a73-be6d-4114-..",
  "message": "Job failed.",
  "project_uid": "xxxxxxx-e8b3-445c-...",
  "error": "Your cookie is not valid. Update your LinkedIn integration's account by clicking on the refresh button if you have installed the extension or update it manually.",
  "recipe_ref": "xxxxxxx-be6d-4114-97d4-...",
  "workflow_uid": "dac53683-dc50-...",
  "workflow_name": "Extract LinkedIn People Profile",
  "job_name": "test invalid cookie"
}

​
Retrying Failed Inputs

Retries depend on the failure reason:
  • Do Not Retry: Issues like 404 errors or incorrect inputs.
  • Retry Possible: Temporary issues such as API timeouts or invalid session cookies.
To retry jobs:
  1. Refresh and resume paused jobs.
  2. Update your cookie or resolve the issue and retry. Retry a Run Guide

​
Retrying a Webhook

You can retry webhooks for:
  • Testing: Re-trigger to validate the integration.
  • Missed Webhooks: Reattempt delivery if the webhook wasn’t triggered.

​
Using the API

To retry a webhook, use the Retry Webhook endpoint: 
curl --request POST \
--url https://api.captaindata.co/v3/webhooks/{job_uid}/retry \
--header 'Authorization: <api-key>' \
--header 'x-project-id: <api-key>'
Replace {job_uid} with the relevant job UID. For detailed instructions, refer to the Retry Webhook Documentation.

​
Retrying in the UI

To retry through the Captain Data app:
  1. Open the specific job by its UID.
  2. Navigate to the Webhooks tab.
  3. Click Retry and paste the job UID to reattempt delivery.
