API Keys

Overview

If a third-party application needs to read or write data in CiviCRM, then you may need to generate an API key.

Each API key is attached to a specific contact record or user account which determines the permissions. When configuring a new application, you should determine the contact ID and double-check their roles or permissions.

Each API key must be unique and difficult to guess. To generate a good API key, use a random sequence of 20+ alphanumeric characters.

Assigning keys

Assuming you have identified a suitable contact record, you may assign a key through any of the following tools:

"API Key" Extension

The optional API Key Extension provides a simplified web interface for managing keys.

APIv3 and APIv4 Explorer

The "APIv3 Explorer" and "APIv4 Explorer" both provide a powerful, built-in way to manipulate CiviCRM data through the administrator interface.

See "Stack Exchange: How do I set up an API key for a user?"

CLI

If you have shell access and cv, then you can generate and assign API keys:

1. Generate a random key:

   head -c32 /dev/urandom | base64 | tr -d '+/='
   

   T0PS3CR3T6ateeUXgTOJ9e3PpXvDZF9Al55WAmBsNQI
   

2. Assign this new value to the contact. In this example, we update contact #100:

   cv api contact.create id=100 api_key="T0PS3CR3T6ateeUXgTOJ9e3PpXvDZF9Al55WAmBsNQI"
   

MySQL

If you have direct access to the MySQL database, then you can generate and assign API keys:

1. Generate a random key:

   SELECT @api_key := REPLACE(REPLACE(REPLACE(
     TO_BASE64(RANDOM_BYTES(32)), "+", ""), "/", ""), "=", "") AS api_key;
   

   +---------------------------------------------+
   | api_key                                     |
   +---------------------------------------------+
   | T0PS3CR3T6ateeUXgTOJ9e3PpXvDZF9Al55WAmBsNQI |
   +---------------------------------------------+
   

2. Assign this new value to the contact. In this example, we update contact #100:

   UPDATE civicrm_contact SET api_key = @api_key WHERE id = 100;
