This is open-sourced API programming code that used by PPI Jerman for organizational purpose.
The API is deployed on Netlify. Currently, there are 2 deployment,
development and production.
The development has the domain netlify-1-dev.ppijerman.org
and deploy the branch development.
The production has the domain netlify-1.ppijerman.org
and deploy the branch master.
This API fetches the post from the Instagram Graph API.
The HTML and (front-end) Javascript code example
can be seen in instagram-posts.html.
The new API specification limit the usage of API by only using OAuth. This causes problem as we cannot fetch directly all data without an access token. To overcome this, we first call the Instagram API endpoint to get the access token and then save them in a database for getting refresh token.
This implementation require that the initial access token is set in the Netlify environment variable. The code assumes that the API is called at least once before the current auth code expired. If the auth code is expired, then there will be error in the code and initial auth code need to be set again (manually).
To prevent the auth code being expired, one can use free cron job service in internet (e.g., https://cron-job.org/) that call the API endpoint every day to make sure that the auth code always refreshed every day.
The application that used for OAuth is maintained by current or previous committees of PPI Jerman.
Make sure at least one committee have access to the application via Instagram developer portal
The database that used for storing auth codes are hosted by PPI Jerman.
The stored auth codes are always encrypted. The cipher that
used to encrypt the auth codes could be asked to current or previous
committee, too. The encryption happens in API side using CryptoJS.
Make sure at least one committee know the cipher or where it is located
