API integrations backend

This repository contains the backend API which is responsible for managing access tokens, checking the heartbeats of deployments, and performing other operational tasks. The system manages tokens two type of tokens: Grafana Loki access tokens and signed API access tokens. The former facilitates the authorization process for partner providers, empowering them to send airnode-feed logs. Meanwhile, the latter type of tokens is used to authorize partner providers to send signed data to signed-api deployed by Nodary and API3. Beyond token management, the system intelligently processes the heartbeat logs from 'airnode-feed' deployments, offering a comprehensive mechanism to assess the status of these deployments.

Getting started

Configuration

  1. Copy .env from the example.env file.
  2. Open the .env file and update the environment variables:
    • HTTP_API_ID: ID of the AWS HTTP API Gateway
    • API_KEY_LIST: List of API keys that are allowed to use the API in the format user1:key1,user2:key2
    • GF_CLOUD_REGION: Region of the utilizied Grafana Cloud instance
    • GF_CLOUD_TOKEN: Grafana Cloud token that is enabled to generate token and read logs
    • GF_CLOUD_ACCESS_POLICY_ID: Policy to be used while generating token, expected to be authorized to write logs only
    • GF_LOKI_USER: Grafana Loki user able to use endpoint GF_LOKI_ENDPOINT
    • GF_LOKI_ENDPOINT: Grafana Loki HTTP API endpoint

Deployment

To deploy infrastructure to AWS:

pnpm run serverless:deploy --region us-east-2 --stage prod

To remove deployment:

pnpm run serverless:remove --region us-east-2 --stage prod

Public endpoint

This service is publicly accessible at the following endpoint:

Usage

The API provides the following endpoints:

  • POST /grafanaLokiAccess: Generate token that will be used to authorize partner providers to send Airnode feed logs
  • GET /grafanaLokiAccess: Get Grafana Loki access token for the given Airnode address
  • DELETE /grafanaLokiAccess: Delete Grafana Loki access token
  • POST /signedApiAccess: Generate token that will be used to authorize partner providers to send signed data
  • GET /signedApiAccess: Get signed API access token for the given Airnode address
  • DELETE /signedApiAccess: Delete signed API access token
  • GET /deploymentStatus: Get status for the deployment

Local development

Start local dynamodb server:

pnpm run local:db:up

Initialize tables:

pnpm run local:db:init

Spin up local express server to mimic AWS API gateway:

pnpm run local:start

You can use following valid examples in the next section to test server.
