What’s new in MemberPress Developer Tools 1.3.10
Version 1.3.10 · Jul 31, 2026
Latest
- FixedFixed a security hole where anyone could delete your Zapier webhook subscriptions. The unsubscribe endpoint didn’t check permissions — now it requires the same login as every other webhook endpoint, and unknown IDs get a clean “not found” instead of wiping settings.
- FixedFixed a SQL injection risk in the REST API. Sort options passed into the API were dropped straight into database queries. Column names and sort direction are now validated in one central place, with safe fallbacks.
- FixedDeleting your last webhook now actually sticks. Removing the final webhook said “saved” but the webhook came back on reload. Fixed.
- ImprovedHardened webhook saving. Bad or malformed webhook data is now rejected with an error instead of silently emptying your webhook list, and slashes in submitted URLs are stripped properly.
- ImprovedUpdated the API docs to match the new unsubscribe behavior.
What it does
Running a membership site often means copying data between systems by hand: new members into a CRM, cancellations into a spreadsheet, signups into an email tool. This add-on gives MemberPress a REST API and a webhook system, so other applications can read membership data and react to events on your site. The result is more control over how your membership business connects to the rest of your tools, with less manual work.
The plugin works in two directions. The REST API lets external apps and custom code query your data, with sort options checked against valid columns and directions. Webhooks push information out to URLs you choose, and Zapier can subscribe to them for no-code automations. All webhook endpoints require a login, malformed webhook data is rejected with a clear error, and API documentation describes how the endpoints behave. It fits developers building custom integrations and site owners comfortable working with automation tools.
Best for
- Developers building custom integrations for MemberPress sites
- Membership site owners automating workflows with Zapier
- Agencies connecting client membership sites to outside applications
Features
REST API for MemberPress
Gives external applications and custom code a REST API for working with your MemberPress data, so you can build integrations that go beyond the built-in settings.
Validated sorting in API queries
Sort options passed to the API are checked in one central place for valid column names and sort direction, with safe fallbacks when a value is not accepted.
Outgoing webhooks
Send data from your membership site to other applications through webhooks, so connected tools can respond automatically when things happen in MemberPress.
Zapier webhook subscriptions
Zapier can subscribe to and unsubscribe from your webhooks, letting you build automations with other apps without writing integration code yourself.
Login-protected endpoints
Every webhook endpoint, including the Zapier unsubscribe endpoint, requires the same login, and unknown subscription IDs return a not found response instead of changing settings.
Careful webhook saving
Bad or malformed webhook data is rejected with an error instead of clearing your webhook list, slashes in submitted URLs are stripped, and deleting your last webhook stays deleted.
API documentation
Included API docs describe how the endpoints behave, including unsubscribe handling, which helps developers plan and test their integrations.

Questions about MemberPress Developer Tools
Does this work without MemberPress?
No. It is an add-on for MemberPress, built to extend a MemberPress membership site with a REST API and webhooks. You need MemberPress running on your site for these developer features to have any membership data to work with.
Can I connect my membership site to Zapier?
Yes. Zapier can subscribe to the plugin's webhooks, so events on your membership site can trigger automations in other apps. Subscribing and unsubscribing go through endpoints that require a login, which keeps outsiders from removing your Zapier connections.
Do I need to be a developer to use it?
The REST API is aimed at developers writing custom code. Webhooks and the Zapier connection are more approachable for technical site owners who are comfortable setting up automations, though some familiarity with how APIs and webhooks work will help.
How does it handle bad webhook data?
Malformed or invalid webhook data is rejected with an error message instead of silently wiping your saved webhooks. Submitted URLs are cleaned of stray slashes, and removing your final webhook is saved properly so it does not reappear on reload.
Is MemberPress Developer Tools free?
The code of MemberPress Developer Tools is licensed under the GPL, so anyone may use, change and share it. GPL Feast is a paid service: a plan or a single purchase gives you the download and automatic updates. The developer's own support, licence key and online services are not included.
Which version of MemberPress Developer Tools is this?
Version 1.3.10, released Jul 31, 2026. New versions appear here when the developer publishes them, and members get them as automatic updates.
How do I update MemberPress Developer Tools?
Install the free GPL Feast Updater on your site and connect it with your API key. It installs new versions of MemberPress Developer Tools automatically and keeps a backup, so you can roll back.
