Usage

Forward

By default the webhooks get forwarded with the original body and the same Content-Type.

# webhooks.yml
my-cool-webhook: # POST http://localhost:8000/my-cool-webhook
  - url: "https://webhook-receiver-1/" 
  - url: "https://webhook-receiver-2/" # Forward to multiple receivers

Filter

Use jinja2 templates to filter the incoming webhooks. If any of the conditions fails the webhook will not be forwarded. You can access the following data from the incoming request: json, headers, form, content(body), query.

# webhooks.yml
my-cool-webhook: # POST http://localhost:8000/my-cool-webhook
  - url: "https://webhook-receiver-3/api/webhook/SAHASDLITZENLXLHS"
    conditions:
      - "{% if json.NotificationUrl.object.Payment.alias.iban == 'DE123123123123213' %}True{% else %}False{% endif %}"
      - "{% if json.NotificationUrl.object.Payment.amount.value|float > 0 %}True{% else %}False{% endif %}"

Transform

# webhooks.yml
my-cool-webhook: # POST http://localhost:8000/my-cool-webhook
  - url: "https://webhook-receiver-1/"
    json:
      amount: "{{ json.NotificationUrl.object.Payment.amount.value }}"
      receiver: "{{ json.NotificationUrl.object.Payment.alias.iban }}"
      sender: "{{ json.NotificationUrl.object.Payment.counterparty_alias.iban }}"
      description: "{{ json.NotificationUrl.object.Payment.description }}"

Custom headers

# webhooks.yml
my-cool-webhook: # POST http://localhost:8000/my-cool-webhook
  - url: "https://webhook-receiver-1/"
    headers:
      x-customer-header: "my-header-value"

All in one

# webhooks.yml
my-cool-webhook: # POST http://localhost:8000/my-cool-webhook
  - url: "https://webhook-receiver-1/"
    headers:
      x-customer-header: "my-header-value"
    json:
      amount: "{{ json.NotificationUrl.object.Payment.amount.value }}"
      receiver: "{{ json.NotificationUrl.object.Payment.alias.iban }}"
      sender: "{{ json.NotificationUrl.object.Payment.counterparty_alias.iban }}"
      description: "{{ json.NotificationUrl.object.Payment.description }}"
      original_header: "{{ headers.x_my_header }}"
      query_param_1: "{{ query.param1 }}"
