I'm trying to list all the variables defined in my GitLab repository (project) using the following API: https://gitlab.com/api/v4/projects/[PROJECT-ID]/variables
But, I don't get all the variables. I can see more variables defined here: https://gitlab.com/[GROUP-NAME]/[PROJECT-NAME]/-/settings/ci_cd
I also checked the following API documentation but didn't find anything to figure out the reason: GitLab > Project-level CI/CD variables API > List project variables
Why is this happening? Is there any bug in GitLab?
Note: [PROJECT-ID], [GROUP-NAME] and [PROJECT-NAME] are placeholders and will be replaced with the actual values.
I have figured it out. It seems like the list project variables API doesn't show more than 20 variables by default. I just made a wild guess of trying out passing a page variable with the API call and it worked. See this: https://gitlab.com/api/v4/projects/[PROJECT-ID]/variables?page=2
On the second page, the remaining (missing) variables appeared which means that they do exist and are accessible.
These details regarding this pagination variable (page) are missing from the official documentation of GitLab's APIs (list project variables).
Note: [PROJECT-ID] is a placeholder and will be replaced with the actual value.
