Memberstack API

Using Memberstack 2.0? There is an updated version of this article here.

The Memberstack API makes it possible for users to retrieve, update, or delete data connected to their websites.

Note: The Memberstack API Beta currently only allows the modification of a website's members.

Important: This is not a front-end API and should only be used in the backend.

Authentication

The Memberstack API uses an API key to authenticate the requests. You can retrieve an API key in the Memberstack dashboard.

The received API key can be added to the X-API-KEY request header.

Javascript:

fetch('https://api.memberstack.com/v1/members', {
  headers: {
    'X-API-KEY': // your API key
  }
})

Curl:

curl -i -H "X-API-KEY: yourapikey" -H "Content-Type: application/json" https://api.memberstack.com/v1/members

Note: Make sure you're not exposing your private API key in a browser environment.

Member Endpoints

The typical response contains the member object, or an array of member objects. The member object contains the following fields:

Membership Object

Note: Source has been deprecated in favor of payment_method and is only available on older members.

List Members

List all members that have a subscription to your website.

Other query parameters include limit to limit the amount of objects that get returned and page that gets the next batch of objects. 

Javascript:

fetch('https://api.memberstack.com/v1/members', {
  headers: {
    'X-API-KEY': 'yourapikey'
  }
}

Curl:

curl -i -H "X-API-KEY: yourapikey" -H "Content-Type: application/json" https://api.memberstack.com/v1/members

Note: metaData can contain up to 50 values. Object keys cannot be longer than 50 characters, object values cannot be longer than 500 characters.

Note: When creating a member please make sure the email is all lowercase.

  'X-API-KEY': 'yourapikey'
 },
 body: JSON.stringify({ 
  email: "...",
  password: "...",
  plan: "...",
  customFields: { 
   userName: "...",
   avatar: "..."
  }
 })
}

Curl:

curl -XPOST -H 'X-API-KEY: yourapikey' -d '{ 
email: "...",
password: "...",
plan: "...",
customFields: {

Live Example

Interact instantly with the API in this Codesandbox embed. In order to be able to use the API endpoints, you'll need to:

• Update the value of API_KEY with the value of your API key.
• Update the value of FREE_PLAN_ID with the id of a free plan on your website. You can get the id of a plan by going to memberships in the dashboard, and extracting the id from the signup link.
• Update the values of the USER_ID_TO_FETCH for the user that will be queried, USER_ID_TO_UPDATE for the user that will be updated, and USER_ID_TO_DELETE for the user that will be deleted.

Note: These values can be the same id. Deleting the user with the id of USER_ID_TO_DELETE will be removed permanently.
