 | |
| //
 | |
| // Update default interaction policies per visibility level for new statuses created by you.
 | |
| //
 | |
| // If submitting using form data, use the following pattern:
 | |
| //
 | |
| // `VISIBILITY[INTERACTION_TYPE][CONDITION][INDEX]=Value`
 | |
| //
 | |
| // For example: `public[can_reply][always][0]=author`
 | |
| //
 | |
| // Using `curl` this might look something like:
 | |
| //
 | |
| // `curl -F 'public[can_reply][always][0]=author' -F 'public[can_reply][always][1]=followers'`
 | |
| //
 | |
| // The JSON equivalent would be:
 | |
| //
 | |
| // `curl -H 'Content-Type: application/json' -d '{"public":{"can_reply":{"always":["author","followers"]}}}'`
 | |
| //
 | |
| // Any visibility level left unspecified in the request body will be returned to the default.
 | |
| //
 | |
| // Ie., in the example above, "public" would be updated, but "unlisted", "private", and "direct" would be reset to defaults.
 | |
| //
 | |
| // The server will perform some normalization on submitted policies so that you can't submit totally invalid policies.
