  description: |
    The Postman Webhooks API enables you to create webhooks that trigger
    collection runs with custom payloads. Webhooks provide a way to integrate
    Postman with external systems and automate workflows based on incoming
    events. When a webhook URL receives a POST request, it triggers a
    collection run with the incoming payload available as variables.

    ## Authentication
    All requests require an API key passed in the `x-api-key` header.

    ## Rate Limits
    Standard Postman API rate limits apply.
