WSO2 Identity Server OTP Email Configuration for SendGrid

I am getting crazy in setting email configuration for sendgrid.

I have followed steps for configuring Email OTP. When I try the email is not being sent & in the logs I find the following exception:

[2019-01-23 13:15:42,756] ERROR {org.wso2.carbon.event.output.adapter.email.EmailEventAdapter} -  Event dropped at Output Adapter 'EmailPublisher' for tenant id '-1234', Error in message format, null

Entire documentation is about how to Configure Gmail as the email OTP provider. I have done configuration based on the understanding I got from basic doc.

Please find configurations under the section in the /repository/conf/identity/application-authentication.xml configurations that I tried:

 <AuthenticatorConfig name="EmailOTP" enabled="true">
        <Parameter name="GmailClientId">gmailClientIdValue</Parameter>
        <Parameter name="GmailClientSecret">gmailClientSecretValue</Parameter>
        <Parameter name="SendgridAPIKey">S********1sLhYrS4_h7J1ehoBWA</Parameter>
        <Parameter name="GmailRefreshToken">gmailRefreshTokenValue</Parameter>
        <Parameter name="GmailEmailEndpoint">https://www.googleapis.com/gmail/v1/users/[userId]/messages/send</Parameter>
        <Parameter name="SendgridEmailEndpoint">https://api.sendgrid.com/api/mail.send.json</Parameter>
        <Parameter name="accessTokenRequiredAPIs">Gmail</Parameter>
        <Parameter name="apiKeyHeaderRequiredAPIs">Sendgrid</Parameter>
        <Parameter name="SendgridFormData">SendgridFormData</Parameter>
        <Parameter name="SendgridURLParams">sc</Parameter>
        <Parameter name="GmailAuthTokenType">Bearer</Parameter>
        <Parameter name="GmailTokenEndpoint">https://www.googleapis.com/oauth2/v3/token</Parameter>
        <Parameter name="SendgridAuthTokenType">Bearer</Parameter>
        <Parameter name="redirectToMultiOptionPageOnFailure">false</Parameter>
    </AuthenticatorConfig>

I think it's not documented well for sendgrid or I am not able to find it. Could anyone provide some reference or solution for the same? Thanks in advance.

Solution

  • This error will be thrown when Gmail blocks an external party to sign in to the account. Turing on 'Less secure app access' at https://myaccount.google.com/security will solve this issue.
