integrator

Intro

Deploy a self-contained service that integrates with the Affix API within your infrastructure.

Affix API follows the OAuth 2.1 specification, which makes integrating as standardised as possible; this does require you coding to our API.

We also offer a no-code solution where we can drop the extracts over SFTP or AWS S3.

Somewhere inbetween is this service, which you can deploy to your cloud and does most of the integration for you.

Quickstart (local)

git clone [e-mail]:affixapi/integrator.git && cd integrator

docker compose up

The service is now running @ localhost:8080

Quickstart (prod + connect your own DB)

docker pull ghcr.io/affixapi/integrator:latest

docker run --rm -it \
  --env-file .env \
  -e DB_CXN_STR=postgres://postgres:affixapi@postgres:5432/affixapi \
  -p 8080:8080 \
  integrator:latest \
  --name integrator \
  npm start

The service is now running @ localhost:8080

environment variables

export CLIENT_ID=''
export CLIENT_SECRET=''
export REDIRECT_URI='http://localhost:8080/callback'
export NODE_ENV=dev
export HOST=0.0.0.0 # interface the node server listens on. either `0.0.0.0` (for server running in docker or accepting non-local traffic) or `localhost` (for local testing)
export PORT=8080

export DB_CXN_STR='postgres://your-username:your-password@your-postgres-host:5432/affixapi' # if not using the postgres docker container
export POSTGRES_PASSWORD='your-postgres-password' # if launched via docker-compose only

dev

npm install
dev-resources/run-db # or configure your own DB with the DB_CXN_STR env var
npm run dev

dev/prod (with docker)

docker pull ghcr.io/affixapi/integrator:latest
# make sure to set the DB_CXN_STR env var the `.env` file
docker compose up

prod (without docker)

git clone [e-mail]:affixapi/integrator.git && cd integrator
npm ci --production

# make sure to set the DB_CXN_STR env var

npm start

Production

You will need to deploy this within your production environment.

Two options:

• use a load balancer for SSL termination, and forward request to a box hosting the service

In AWS speak, set up an Application Load Balancer (ALB), forward port 80 to port 443, and forward port 443 to either an EC2 box hosting the service, or one of the many AWS services (AWS Fargate, etc) that can host a docker container

• create an SSH certificate

Next steps

• Create a persistent database connection; either to your existing main database or a microservice data. Ensure that only respective teammates can access, as Affix tokens will be stored inside this DB.
• Use a Key Management Service (such as AWS KMS) to store the Affix API keys in the DB as ciphertext. This ensures that even in the unlikely event of data exfiltration, the keys are not usable by non-internal team members.
• Use a database connection pool
