Hi all, I'm trying to see if I can use Medplum's Typescript libraries to authenticate and connect to an Epic Sandbox I've created (with ClientID and ClientSecret) I came across this Medplum post, where it looks like Codex has done something very similar: https://www.medplum.com/blog/codex-and-the-power-of-g10 At the bottom of the article, in the "How it Works" section, there's a snippet of Typescript code showing how it would be done. In my own attempt to reproduce this, I notice that the "startLogin()" function in the article defines parameters for "ClientId" and "ClientSecret". However, when I try to use the same bits of code, the "startLogin()" seems to expect only a username and password. Indeed, the "Related Resources" section at the very bottom of the article points to "Medplum SDK startLogin" => This link is broken. I was able to find the startLogin for username/password version here: https://www.medplum.com/docs/sdk/classes/MedplumClient#startlogin But alas, I can't find documentation for external Ehr Login that supports the code from the article. Any help/direction would be greatly appreciated. Thank you!

I've just been using the OAuth endpoint to get a token with my client id/secret https://www.medplum.com/docs/api/oauth/token

To clarify, I'm not trying to connect to my own Medplum instance. I'm trying to connect to my Epic Sandbox. Unless I'm misunderstanding the provided link, this looks like requesting a token from Medplum's endpoint, which is not what I'm trying to do.

Oh my bad, didn't know you could use medplum's SDK like that

No worries. But I think that too is specifically for connecting to Medplum. Looking at the example in the comments of that function, the clientId and secret are named: "process.env.MEDPLUM_CLIENT_ID" and "process.env.MEDPLUM_CLIENT_SECRET" I don't think that function works for anything other than auth to Medplum directly.

hey Joshua, the client supports multiple kinds of flows with different kinds of credentials - I'll send you a DM

@reshma Can you send me a DM as well? I am trying to get it to work with Epic and Cerner (or others) as a POC.

Hey @ngtsmythe_50107 ! Since this was written there have been a few published implementations for these use cases. I recommend watvhing these as well:

Thanks for this! I work for a company that might enter into the EHR space and we are trying to get a sense on LOE to connect to patient data from various sources.
