Intermittent Invalid Login Credentials using API

[dcockburn]

Hello, hoping someone can help.

I am using the QuickFile API v1.2, with a NodeJS application.

It works OK the majority of the time, but on occasion, it returns an error with the value: ‘Invalid Login Credentials’?

I know that the MD5 is generating fine, because it works one minute, and not the next?

What is happening here? Is the API limited to a number of requests per minute (or similar)?

Hi @dcockburn

There are no time limits in that respect, only a daily limit (default 1,000 per day).

Do you have any examples of requests that have failed, and their responses? You’re welcome to send it to @QFSupport in a private message if they contain sensitive data (including your credentials).

the previous request sent moments earlier with the same code returned:

@QFMatthew any idea what could be causing this?

@dcockburn - I’ve replied to your private message.

This has been resolved. My submission ID was being generated using the current Date in milliseconds, appended with a random 4 digit number following a decimal point. It would appear that the API doesn’t like the decimal. I have amended my code to remove the decimal point and the issue is resolved. Thank you to QF for the quick support!
