Use CI/CD Pipeline in Gitlab to periodically retrieve data from a REST endpoint and save to Gitlab repo

Question

I've got a Dash Enterprise app that uses some monthly data reports. Every month I manually upload the new data files which are stored at a Rest endpoint. I want to automate this process using GitLab. Can the GitLab CI/CD Pipeline retrieve data from a REST endpoint and upload it to the GitLab repo?

I was thinking something like this:

1. YAML file specifies a stage in the pipeline that runs a python script
2. The python script pulls the data from the REST endpoint example: data = requests.post('<some rest endpoint url>', params=dict(criteria='foo')).json()
3. Somehow python or the YAML file pushes this data to the GitLab repo.

Is this possible or am I using the wrong tool for the job?

I've created a GitLab repo and created a CI/CD pipeline. I create a job in the YAML file that calls a python file which can pull data from the REST endpoint. I just don't know how this data can be pushed to the GitLab repo that the YAML and python files reside in.
