How to get OAuth2 access token from OAuth1 token and secret with API v2
hi,
While creating an OAuth2 access token from OAuth1, I am getting error saying
Error in call to API function "auth/token/from_oauth1": Invalid value in HTTP header "Authorization": "Be...
Apologies for the confusion. The curl example in the documentation and API Explorer for /2/auth/token/from_oauth1 are unfortunately incorrect. I'll let the team know to fix that.
That endpoint actually uses app authentication ( https://www.dropbox.com/developers/reference/auth-types#app ), so a bearer access token isn't necessary. This is what the curl example should look like:curl -X POST https://api.dropboxapi.com/2/auth/token/from_oauth1 \ -u "APP_KEY:APP_SECRET" \ --header "Content-Type: application/json" \ --data "{\"oauth1_token\": \"OAUTH1_TOKEN_KEY\",\"oauth1_token_secret\": \"OAUTH1_TOKEN_SECRET\"}"
i couldn't get token in both of the ways .
https://www.dropbox.com/developers/reference/auth-types#app - tried . not working . it throws error like v1_retried.
https://www.dropbox.com/developers/documentation/http/documentation#auth-token-from_oauth1 - it always throws invalid client info . i need to get access token using typescript on server side . can you provide
solution for this issue ?

Dropbox Staffjayanthi123 The "OAuth 1" functionality discussed in this thread is only for converting pre-existing old OAuth 1 access tokens to OAuth 2. If you're just starting now, you wouldn't have any OAuth 1 tokens and so shouldn't use that.
Instead, to get an OAuth 2 access token for the end-user, you should implement and use the OAuth app authorization flow. You can find information on that in the Dropbox OAuth Guide, and the Dropbox OAuth 2 documentation. Specifically, that involves the user of the 'www.dropbox.com/oauth2/authorize' page, documented here, and possibly the /oauth2/token endpoint, documented here, depending on which OAuth flow you're using.
I also highly recommend using one of the official SDKs, if possible, as they'll do much of the work for you.
