PostPost

Zapier

Connect PostPost to 5,000+ apps using Zapier's Webhooks feature.

}

Handling Responses

Success Response

PostPost returns:

{
  "success": true,
  "postGroupId": "pg_abc123xyz"
}

You can use Zapier's Paths or Filter to handle this:

  • Continue workflow if success is true
  • Send alert if success is false

Error Handling

Add a Paths step after the webhook:

Path A: If success equals true

  • Continue with success actions (e.g., update spreadsheet, send Slack notification)

Path B: If success does not equal true

  • Send error notification via email or Slack
  • Log to error spreadsheet

Finding Your Platform IDs

To get your platform connection IDs for Zapier:

Option 1: Use the API

curl https://api.postpost.dev/api/v1/platform-connections \
  -H "x-api-key: YOUR_API_KEY"

Option 2: Zapier Webhook GET

Create a simple Zap:

  1. Trigger: Schedule by Zapier → Every Day
  2. Action: Webhooks by Zapier → GET
  3. URL: https://api.postpost.dev/api/v1/platform-connections
  4. Headers: x-api-key: YOUR_API_KEY

Run it once and check the response to get your platform IDs.


Tips and Best Practices

  1. Test First: Always use Zapier's test feature before enabling a Zap
  2. Rate Limits: Add a 1-second delay between multiple webhook calls
  3. Error Notifications: Set up email alerts for failed Zaps
  4. Content Length: Be mindful of platform character limits (Twitter: 280, LinkedIn: 3000, etc.)
  5. Scheduling: Use ISO 8601 format for scheduledTime (e.g., 2026-03-01T14:00:00.000Z)

Common Issues

"Invalid API Key"

  • Check that your API key is correctly entered in the headers
  • Ensure there are no extra spaces

"Invalid Platform ID"

  • Verify your platform IDs using the GET /platform-connections endpoint
  • Platform IDs look like twitter-123456789 or linkedin-ABC123DEF

"Scheduled time is in the past"

  • Make sure your scheduledTime is in the future
  • Use UTC timezone (ends with Z)
