Mux JWT helper does not support playback_restriction_id

[paul-uz]

According to step 4, https://docs.mux.com/guides/video/secure-video-playback#4-generate-a-json-web-token, the playback_restriction_id can be added to the JWT claims, yet the Mux JWT helper does not accept a playback_restriction_id anywhere.

How can I add playback_restriction_id to the JWT signing process?

Hey @paul-uz,

Sorry you're right this isn't clear.

You should be able to set this in the params hash, like in the example on this page: https://docs.mux.com/guides/video/secure-video-playback#5-sign-the-json-web-token-jwt

const { JWT } = require('@mux/mux-node');

const playbackId = ''; // Enter your signed playback id here

let baseOptions = {
  keyId: '',     // Enter your signing key id here
  keySecret: '', // Enter your base64 encoded private key here
  expiration: '7d' // E.g 60, "2 days", "10h", "7d", numeric value interpreted as seconds
};

const token = JWT.sign(playbackId, { ...baseOptions , type: 'video'});

const gifToken = JWT.sign(playbackId, {
  ...baseOptions,
  type: 'gif',
  params: { time: 10,  playback_restriction_id: 'PLAYBACK_RESTRICTION_ID'},
})

Let me know if this works.

Thanks!

Hi @philcluff that seems to work.

I first tried added it to the baseOptions, but that didn't work. Adding it to params did the trick.

Could you please look at updating the documentation with this information?

Glad it worked for you, I've asked the team here to either update the docs and/or add this to the helper explicitly.

Thanks!
