It's not triggerring after 
signinup/code/consume
api is successful? Am I doing something wrong?

Hi @ggi_d , The signinup post API does not trigger for the consume code flow. @sattvikc can help you with the snippet for the actual override
Also note that you do not need to init the thirdparty recipe separately if you are using thirdpartypasswordless
g
So I can use something like this?
Basically what I'm trying to achieve is, although using different signup/in methods, I want to map the user to one common user in my DB using email as the primary identifier. I'd want to map the user id to this method as well.
Hi @sattvikc , also is there a way to get user's by email from the supertoken db or just merge the passwordless auth with social auth?
n
Ah right, so account linking as a feature is something we are working on at the moment. In the meantime one way to do it is to override the consume code and sign in up methods and check if a user already exists with that email (you can do this by mapping it yourself or using our helper function to get a user by email), then you can use the userContext feature to pass the user id to the function that creates the session
@sattvikc Can we share a quick example of what the code would look like for this?
s
yea sure
give me a min, going thru the conversation once again
will share an example in a little while.. m on it
g
So I'm overriding the 
ConsumeCodePOST
method, how do I get the user's email here from the parameters?
s
in the API overrides, you can get email after calling the original implementation, from the OK result
g
okay thanks!
s
you could override the recipe functions as follows to achieve what you need:
Copy code
Override: &tplmodels.OverrideStruct{
    Functions: func(originalImplementation tplmodels.RecipeInterface) tplmodels.RecipeInterface {
        oConsumeCode := *originalImplementation.ConsumeCode
        nConsumeCode := func(userInput *plessmodels.UserInputCodeWithDeviceID, linkCode *string, preAuthSessionID string, userContext supertokens.UserContext) (tplmodels.ConsumeCodeResponse, error) {
            res, err := oConsumeCode(userInput, linkCode, preAuthSessionID, userContext)
            if err != nil {
                return res, err
            }
            if res.OK != nil {
                if res.OK.CreatedNewUser {
                    externalUserID := getExternalUserIDForEmail(res.OK.User.Email)
                    supertokens.CreateUserIdMapping(res.OK.User.ID, externalUserID, nil, nil)
                }
            }
            return res, err
        }
        *originalImplementation.ConsumeCode = nConsumeCode

        oThirdPartySignInUp := *originalImplementation.ThirdPartySignInUp
        nThirdPartySignInUp := func(thirdPartyID string, thirdPartyUserID string, email string, userContext supertokens.UserContext) (tplmodels.ThirdPartySignInUp, error) {
            res, err := oThirdPartySignInUp(thirdPartyID, thirdPartyUserID, email, userContext)
            if err != nil {
                return res, err
            }
            if res.OK != nil {
                if res.OK.CreatedNewUser {
                    externalUserID := getExternalUserIDForEmail(res.OK.User.Email)
                    supertokens.CreateUserIdMapping(res.OK.User.ID, externalUserID, nil, nil)
                }
            }
            return res, err
        }
        *originalImplementation.ThirdPartySignInUp = nThirdPartySignInUp
        return originalImplementation
    },
},
you will need to implement 
getExternalUserIDForEmail
to get or create user ID for each email on your db.
we are also working on the Account linking feature to make these use cases possible with our SDKs.

Thanks so much for this!!!
Also, what argument does the 
GetUserIdMapping
function take? My (External) User ID or the Supertoken User ID?
s
either of them
it has userIdType parameter which can be one of these
@ggi_d seems like what I suggested isn't the right solution, give me a little while, I'll get back
g
sure sure! 👍
s
there is a similar situation here - https://discord.com/channels/603466164219281420/1013756565561557052/1014096025268535317 - would u be able to try this approach?
