There are plenty of free APIs you can use for learning - https://github.com/toddmotto/public-apis/ More on reddit.com

Using an API just comes down to making a request to the right end-point (e.g. /api/v1/me), which then returns data. Most of the time this data is in either JSON or XML format.

Now in order to view that end-point (/api/v1/me) you need to be authenticated via OAuth, which is a whole separate process. (But also including making requests by sending the right data back and forth.)

Now to make it easy, you can just use PRAW. Which has a small tutorial on their website. :)

Read this to get the access token up and running. Here is information about submitting a post to a sub. There is information about getting the modhash as well. I've not tested this, just typed it up based on the docs: const baseUrl = "https://www.reddit.com/api/v1/" const username = "My-Url_Bot" const password = "DivingWithSharks" const client_id = "client" const client_secret = "secret" function PostToReddit(urls) { const modhash = "xxxx" const date = Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "yyyy-MM-dd") const title = `New urls ${date}` const body = ` Hi Folks, Here is a list of new urls: **Urls** :-- ` urls.flat().forEach(u => body += `${u}\n`) const payload = { ad: false, api_type: "json", flair_id: "TheFlairId", nfsw: false, spoiler: false, sr: "YoureSub", text: body, title: title } const params = { method: "POST", headers: { "Content-Type": "application/json", "X-Modhash": modhash, "Authorization": "bearer " + getAccessToken_() }, payload: JSON.stringify(payload) } const response = UrlFetchApp.fetch(base + "submit", params) console.log(response.getContentText()) } function getAccessToken_() { const payload = { grant_type: "password", username: username, password: password } const params = { method: "POST", headers: { "Authorization": "Basic " + Utilities.base64Encode(client_id + ":" + client_secret) }, payload: JSON.stringify(payload) } const response = UrlFetchApp.fetch(baseUrl + "access_token", params) const data = JSON.parse(response.getContentText()) return data.access_token } More on reddit.com

On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge. If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options: Limiting your involvement with Reddit, or Temporarily refraining from using Reddit Cancelling your subscription of Reddit Premium as a way to voice your protest.
