How do I get invitation code on TestFlight?

Whatever developer is offering access to there test application has to send you a code.

Apple doesn’t do it and nobody here at this user to user support forum has it or can send you one.

Test flight doesn’t have a support forum. The developer might have an online community or forum. Please contact the developer that hosts the forum you want access to.

Since you don’t seem to know what TestFlight is:

https://testflight.apple.com/

Getting started

To test beta versions of apps and App Clips using TestFlight, you’ll need to accept an email or public link invitation from the developer and have a device that you can use to test. You’ll be able to access the builds that the developer makes available to you.

Whatever invitation code you are looking for is not here. Instead if you have a technical question for us, go right ahead.

We are a support forum, but a technical support forum regarding Apple products and services. What you are asking we have no control over.
