Affix API
2023-03-01

The affixapi.com API documentation.

Introduction

Affix API is an OAuth 2.1 application that allows developers to access customer data, without developers needing to manage or maintain integrations; or collect login credentials or API keys from users for these third party systems.

OAuth 2.1

Affix API follows the OAuth 2.1 spec.

As an OAuth application, Affix API handles not only both the collection of sensitive user credentials or API keys, but also builds and maintains the integrations with the providers, so you don't have to.

How to obtain an access token

in order to get started, you must:

  • register a client_id
  • direct your user to the sign in flow (https://connect.affixapi.com with the appropriate query parameters)
  • capture authorization_code we will send to your redirect URI after the sign in flow is complete and exchange that authorization_code for a Bearer token

Sandbox keys (xhr mode)

Compression

We support brotli, gzip, and deflate compression algorithms.

To enable, pass the Accept-Encoding header with one or all of the values: br, gzip, deflate, or identity (no compression)

In the response, you will receive the Content-Encoding response header indicating the compression algorithm used in the data payload to enable you to decompress the result. If the Accept-Encoding: identity header was passed, no Content-Encoding response header is sent back, as no compression algorithm was used.

Webhooks

An exciting feature for HR/Payroll modes are webhooks.

If enabled, your webhook_uri is set on your client_id for the respective environment: dev | prod

Webhooks are configured to make live requests to the underlying integration 1x/hr, and if a difference is detected since the last request, we will send a request to your webhook_uri with this shape:

{

  added: <api.v20230301.Employees>[
    <api.v20230301.Employee>{
      ...,

}

the following headers will be sent with webhook requests:

x-affix-api-signature: ab8474e609db95d5df3adc39ea3add7a7544bd215c5c520a30a650ae93a2fba7

x-affix-api-origin:  webhooks-employees-webhook

user-agent:  affixapi.com

Before trusting the payload, you should sign the payload and verify the signature matches the signature sent by the affixapi.com service.

This secures that the data sent to your webhook_uri is from the affixapi.com server.

The signature is created by combining the signing secret (your client_secret) with the body of the request sent using a standard HMAC-SHA256 keyed hash.

The signature can be created via:

  • create an HMAC with your client_secret
  • update the HMAC with the payload
  • get the hex digest -> this is the signature

Sample typescript code that follows this recipe:

import { createHmac } from 'crypto';

export const computeSignature = ({
  str,
  signingSecret,
}: {
  signingSecret: string;
  str: string;
}): string => {
  const hmac = createHmac('sha256', signingSecret);
  hmac.update(str);
  const signature = hmac.digest('hex');

  return signature;
};

While verifying the Affix API signature header should be your primary method of confirming validity, you can also whitelist our outbound webhook static IP addresses.

Rate limits

Open endpoints (not gated by an API key) (applied at endpoint level):

  • 15 requests every 1 minute (by IP address)
  • 25 requests every 5 minutes (by IP address)

Gated endpoints (require an API key) (applied at endpoint level):

  • 40 requests every 1 minute (by IP address)
  • 40 requests every 5 minutes (by client_id)

Things to keep in mind:

  • Open endpoints (not gated by an API key) will likely be called by your users, not you, so rate limits generally would not apply to you.
  • As a developer, rate limits are applied at the endpoint granularity.
    • For example, say the rate limits below are 10 requests per minute by ip. from that same ip, within 1 minute, you get:
      • 10 requests per minute on /orders,
      • another 10 requests per minute on /items,
      • and another 10 requests per minute on /identity,
      • for a total of 30 requests per minute.
