correct steps of using the github/octonode API to upload and commit a zip

I am trying to push a zip file to github from a bitbucket pipeline using nodejs

Currently using octonode a nice github api wrapper.

What I am trying to figure out is the process/steps on how to do this.

I was successful in programmatically creating the initial commit

 var github = require('octonode');
 
 const client = github.client(access_token);
 
 const repo = client.repo('myuser/myrepo');
 
 repo.createContents('my.zip', 'Initial Commit', zipFile, (err, data, headers) => {
       
  });

But what to do next is where i end up in the weeds.

I was thinking, creating a branch off of master and then updating the zip file in that branch and then merge.

I can not seem to create a branch. I think i am suppose to use createReference, and suppose to use the sha of master??

By i can not find the sha of master.

repo.createReference('v1.0.0', 'sha', (err, data, headers) => {
      console.log('in createReference callback---err---->', err);
      console.log('in createReference callback---data---->', data);
      console.log('in createReference callback---headers---->', headers);
});

The question is, is this the correct method??

my end goal , is to programmatically push a new zip file to github.

Thanks for any help/suggestions

I am not sure if this is the best way, but this is how i got it to work

   const octokit = new Octokit.Octokit({
        auth: access_token
    });


    const base64Content = utilService.base64Encode(fs.readFileSync(`${zipFilePath}/${zipFileName}`));

    let newBranch = pluginVersionFromFile;

     */

            masterSha = _.get(branch, 'commit.sha');
        }
        if (branch.name === newBranch) {
            newBranch = newBranch + '.' + moment().format('X');
        }
    });
