Setting Up Particle Webhook for Edge Impulse Ingestion

This guide supplements the tutorial on OTA Model Updates with Edge Impulse on Particle Workbench, focusing on configuring a Particle webhook for sending data to the Edge Impulse ingestion API.

​
Steps for Webhook Configuration:

  1. Access Particle Console:
  2. Navigate to Integrations:
    • Click on the “Integrations” tab in the left-hand menu.
    • Select “Webhooks” from the available options.
  3. Create a New Webhook:
    • Click “New Integration”.
    • Choose “Webhook”.
  4. Webhook Configuration:
    • Name: Assign a descriptive name to your webhook.
    • Event Name: Specify the event name that triggers the webhook (e.g., “edge/ingest”).
    • URL: Set this to the Edge Impulse ingestion API URL, typically something like https://ingestion.edgeimpulse.com/api/training/data.
    • Request Type: Choose “POST”.
    • Request Format: Select “Custom”.
  5. Custom Request Body:
    • Input the JSON structure required by Edge Impulse. This will vary based on your project’s data schema.
  6. HTTP Headers:
    • Add necessary headers:
      • x-api-key: Your Edge Impulse API key.
      • Content-Type: “application/json”.
      • x-file-name: Use a dynamic data field like {{PARTICLE_EVENT_NAME}}.
  7. Advanced Settings:
    • Response Topic: Create a custom topic for webhook responses, e.g., {{PARTICLE_DEVICE_ID}}/hook-response/{{PARTICLE_EVENT_NAME}}.
    • Enforce SSL: Choose “Yes” for secure transmission.
  8. Save the Webhook:
    • After entering all details, click “Save”.
  9. Test the Webhook:
    • Use example device firmware to trigger the webhook.
    • Observe the responses in the Particle Console.
  10. Debugging:
  • If errors occur, review the logs for detailed information.
  • Ensure payload format aligns with Edge Impulse requirements.
  • Verify the accuracy of your API key and other details.

​
Custom Template Example:

Copy and paste the following into the Custom Template section of the webhook: 
{
    "name": "edgeimpulse.com",
    "event": "edge/ingest",
    "responseTopic": "",
    "disabled": true,
    "url": "http://ingestion.edgeimpulse.com/api/training/data",
    "requestType": "POST",
    "noDefaults": true,
    "rejectUnauthorized": false,
    "headers": {
        "x-api-key": "ei_1855db...",
        "x-file-name": "{{PARTICLE_EVENT_NAME}}",
        "x-label": "coffee"
    },
    "json": "{\n  \"payload\": {\n    \"device_name\": \"0a10a...\",\n    \"device_type\": \"photon2\",\n    \"interval_ms\": 20,\n    \"sensors\": [\n      {\n        \"name\": \"volt\",\n        \"units\": \"V\"\n      },\n      {\n        \"name\": \"curr\",\n        \"units\": \"A\"\n      }\n    ],\n    \"values\": [\n{{{PARTICLE_EVENT_VALUE}}}\n    ]\n  },\n  \"protected\": {\n    \"alg\": \"none\",\n    \"ver\": \"v1\"\n  },\n  \"signature\": \"00\"\n}"
}
[]: # (end)
