I have a MySQL database configured for remote access with SSL/TLS encryption and I’m trying to integrate it with Zapier automation platform. The database accepts connections from multiple IP addresses and has very open permission settings.
Current database permissions:
GRANT USAGE ON *.* TO 'api_user'@'%' IDENTIFIED BY PASSWORD '*****' REQUIRE SSL
GRANT ALL PRIVILEGES ON `api_user`.* TO 'production_db'@'%'
The connection test in Zapier passes successfully, but when I try to load table names in the dropdown menu, I get this error:
Error message: “We’re having trouble loading ‘Table’ data… internal returned (401) Unauthorized”
The error trace shows: OperationalError: (pymysql.err.OperationalError) (1045, u"Access denied for user 'api_user'@'ec2-54-86-9-50.compute-1.amazonaws.com' (using password: YES)")
When I manually enter a table name and try a basic query like:
SELECT * FROM students
I get another 401 Unauthorized error during the test step. The initial connection works fine but any actual data operations fail. Has anyone experienced similar authentication issues with MySQL and Zapier integration?
totally get you, i had the same thing happen. make sure api_user has access to the specific tables you’re trying to query. also, double-check the SSL certs if they’re set up right. good luck!
You’ve got a user mismatch in your grants. You’re giving USAGE to ‘api_user’ but then granting database privileges to ‘production_db’. Pick one user and stick with it. Try GRANT ALL PRIVILEGES ON your_database_name.* TO ‘api_user’@‘%’ instead. That REQUIRE SSL clause can mess with Zapier connections too. I’d create a test user without SSL first, get everything working, then add SSL back. The 401 error usually means your user can connect but doesn’t have the right table permissions.
check your mysql logs when zapier connects - u’ll probably see the actual error there. that 401 is just zapier’s generic response whenever mysql throws any error. my guess is your ssl config’s rejecting the connection after the handshake goes through.
Had the same problem with MySQL and Zapier recently. The connection test only checks basic access, but actual operations need specific permissions. Your setup’s got a mismatch - you’re giving USAGE to ‘api_user’ but database privileges to ‘production_db’. Fix this by making sure ‘api_user’ has proper database access. Also, Zapier needs SELECT on information_schema to show table names correctly. Try: GRANT SELECT ON information_schema.* TO ‘api_user’@‘%’. Still stuck? Drop REQUIRE SSL temporarily to see if it’s a permissions issue or SSL problem.
Zapier’s MySQL integration is trash with SSL. I’ve hit this same wall multiple times.
It’s not just your user permissions - though fix those too. Zapier uses rotating IPs and can’t handle SSL certificate validation properly with MySQL.
Honestly? Just use Latenode instead. I ditched Zapier after weeks of this nonsense and haven’t looked back. Latenode actually works with MySQL SSL connections.
No weird permission hoops to jump through, and you get real error messages instead of useless 401s.
Last month I built a workflow pulling from our production MySQL (SSL required) to three different services. 20 minutes vs what would’ve been days fighting Zapier.
