Shri's Blog: Send an email using send grid from Logic APP with HTTP trigger

Logic app has many connectors to integrate with. I am going to talk about SendGrid third party connector in this blog. SendGrid is used to send emails, good thing about it that you get 100 emails/day free to play with. You can get more idea about SendGrid from its website https://sendgrid.com/

We are going to create a Logic APP which will call SendGrid connector and send an email to user.

SendGrid Account:

We have to create a SendGrid account in order to connect it with Logic APP. I am using free one, but you can create a paid one which has more feature obviously.

· Signup with SendGrid

· Verify your user account and sender email, you can follow the process from its website

· After login you can see “API Keys” on left hand side menu bar

· Create an API Key

· Check your level, I have given full access.

· You will get the Key but make sure you copy this otherwise it won’t be visible again and you have to create a new one.

Logic APP:

· Create a Logic APP, I have created a consumption based with name of “send-email-sendgrid”

· Use Trigger as HTTP as mentioned below

· Once selected as HTTP, you need to pass request payload schema, I don’t have one so created by providing the JSON sample

{
   "Name":"name",
   "Subject":"test",
   "FromEmail":"sender@gmail.com",
   "ToEmail":"receiver@gmail.com",
   "EmailBody":"email body",
   "Company":"companyname",
   "PhoneNUmber":"0123456789",
   "Address":"Wellington"
}

· Make sure you also add HTTP method as POST

· Click on “New Step” and search “SendGrid” connector in it.

· Click on “Send Email (V4)” action as per below screenshot

· You will be asked to create a connection

· Give a connection name and the Key value which was created in earlier step in SendGrid account

· I have given connection name as “sendgridconn” and pasted my SendGrid API key

· Click on “Create” button

· Once connection is created you will see below window, where you have to provide email details

· As soon as you click on any textbox you will see below window and select respective parameter

· In case you don’t see this click on “see more” link

· Make sure you assign right parameter on right place as these are dynamic parameters which will come from the JSON request.

· Now you can add one more connector so that we can send response back to consumer.

· Search “Response” in connector window and choose “Response” connector as per above screenshot

· Provide Status Code as 200 and “Body” content as below or choose “Name” from window.

{
   "status": "Email has been sent successfully to @{triggerBody()?['Name']}"
}

· Save the logic app and go to HTTP connector, it will create a HTTP URL for you to trigger this Logic APP

· Open your favorite API testing tool and try to test it, I am using POSTMAN tool.

· Pass the below payload for testing and change the values accordingly

{
   "Name":"name",
   "Subject":"test",
   "FromEmail":"<sender_email>",
   "ToEmail":"receiver_email",
   "EmailBody":"email body",
   "Company":"companyname",
   "PhoneNUmber":"0123456789",
   "Address":"Wellington"
}
