Marketing API

Get Started

If your business has a firewall for outbound requests, see Crawler IPs and User Agents to get Facebook's IP addresses. Be aware that the list of addresses changes often.

Sending both action_source and client_user_agent parameters for all of the events you’re sending through the Conversions API may help improve event matching and could also help improve ad delivery for any ad campaigns optimizing on the events you send through the Conversions API.

Requirements

Pixel

Before implementing Conversions API, make sure you have the Facebook pixel correctly implemented in your website. We recommend that you use the same pixel for your browser and server events.

Business Manager

You also need a Business Manager to use the API. Business Manager helps advertisers integrate Facebook marketing efforts across their business and with external partners. If you don't have a Business Manager yet, see the Help Center article on how to Create a Business Manager.

Access Token

To use the Conversions API, you need an access token. There are two ways of getting your access token:

Via Events Manager (Recommended)

To use the Conversions API, you need to generate an access token, which is passed as a parameter in each API call. Inside Events Manager, follow these steps:

  • Step 1 — Choose the pixel you want to implement.
  • Step 2 — Select the Settings tab:
  • Step 3 — Find the Conversions API section and click on Create Access Token under Set up manually, and follow the instructions pop up:

Once you have your token, Events Manager gives you access to a new tab called Implementation.

Navigate to the Implementation tab and follow the instructions displayed in the screen. This way, we automatically create a Conversions API App and Conversions API System User for you. There is no need to go through app review or request any permissions.

Using Your Own App

If you already have your own app and your own system user, you can generate your token inside Business Manager. To do that:

  • Step 1: Go to your Business' Settings.
  • Step 2: Assign a pixel to your system user (you also have an option to create a new system user at this stage).
  • Step 3: Select the assigned system user and click Generate Token.

Your app does not need to go through app review. You do not need to request any permissions.
