Mattermost Details → Post Undefined

AI-generated

Overview

This node allows sending a custom JSON payload to the Mattermost Details resource using a POST operation with an undefined or flexible endpoint. It is designed for scenarios where you want to post detailed information or messages to Mattermost channels by specifying the exact JSON structure of the request body.

Typical use cases include:

  • Posting complex or customized notifications to one or more Mattermost channels.
  • Integrating Mattermost messaging with other systems by sending structured JSON data.
  • Automating Mattermost message posting with dynamic content defined at runtime.

For example, you might send a JSON object specifying multiple channels and message details to notify teams about system alerts or updates.

Properties

Name Meaning
Body The JSON-formatted request body to send in the POST request. This should be a valid JSON string representing the payload, typically including channel information and message details. Example default value: {"channels": [{}]}

Output

The node outputs an array of JSON objects corresponding to each input item processed. Each output item contains:

  • json: The parsed JSON response returned from the Mattermost API after posting the provided body.
  • If an error occurs and "Continue On Fail" is enabled, the output will contain an error field with the error message instead of the expected response.

No binary data output is produced by this node.

Dependencies

  • Requires an API key credential for authenticating with the Mattermost service.
  • The node expects a base URL and authentication credentials (tenant, client ID, client secret) configured in the credentials.
  • Uses HTTP POST requests with JSON bodies to communicate with the Mattermost API.

Troubleshooting

  • Invalid JSON in Body: If the JSON in the "Body" property is malformed, the node will throw a parsing error. Ensure the JSON is valid before running.
  • Authentication Errors: Missing or incorrect API credentials will cause authentication failures. Verify that the API key and related credentials are correctly set up.
  • API Endpoint Issues: Since the operation is "Post Undefined," ensure the JSON body matches the expected schema for the target Mattermost API endpoint.
  • Network or Permission Errors: Check network connectivity and permissions for the API user if requests fail.
  • Error Handling: Enable "Continue On Fail" to allow the workflow to proceed even if some requests fail; errors will be included in the output JSON.
