I want to encourage my users to upload an avatar via api. How can I know a user is using default avatar in discourse? because I don’t want to warn users that already have gravatars or their custom avatars set. ---

I don’t know if its a good solution, but my solution for now is to look for `gravatar_avatar_upload_id` and `custom_avatar_upload_id` in `/users/{username}.json` and to see if they are both set to `null`. Any idea? ---

I think it is the correct solution for you. For my knowledge only three types of avatars are there in Discourse (letter, gravatar and custom avatars). So it must work. ---

Out of curiosity: do you know we already show a JIT message to users with default avatar? > ---

Yes I know. But I have implemented discourse in my application and users mostly post there. So i don’t know If this JIT message could be get with an api call. If it could be, I can call it when users perform some actions inside the application. But if it couldn’t be called with api call, I need to write a custom code for it. ---

> [@hnaseri](#): > > So i don’t know If this JIT message could be get with an api call. These education messages are associated with the composer. I don’t know the exact endpoint, but I’m pretty sure you can get them via the API since it’s working in Discourse 😉 ---

So how should I reverse engineer it? Any idea? I need to make an account without avatar and wait for this message to appear? This is somehow awkward. ---

> [@zogstrip](#): > > The endpoint is /composer\_messages.json 😉 Thank you very much. But how I can actually use it? 🤔 For example when user write their first topic in my app, I want to call this JIT and show the message. ---

To figure out the list you can use [data explorer](https://meta.discourse.org/t/32566?silent=true): ```plaintext SELECT id user_id from users WHERE uploaded_avatar_id IS NULL ``` ---
