PassKit Golang Quickstart

Overview

This quickstart aims to help get Golang developers up and running with the PassKit SDK as quickly as possible.

Prerequisites

You will need the following:

• A PassKit account (signup for free at PassKit)
• Your PassKit SDK Credentials (available from the Developer Tools Page)
• Apple wallet certificate id (for flights only, available from the certificate page)
• Recommended code editor Golang (Guide to installation)

Configuration

1. Install PassKit Golang SDK in the terminal with go install github.com/PassKit/passkit-golang-grpc-sdk It should output something similar to below:

2. In the certs folder of the repository add the following three PassKit credential files:

   • certificate.pem
   • ca-chain.pem
   • key.pem

   You can disregard the key-java.pem credentials file as it is not compatible with Golang.

3. Now we need to decrypt your key.pem. At your project root directory in the terminal, run cd ./certs openssl ec -in key.pem -out key.pem. If you are in your root directory the terminal should show PASSKIT-GOLANG-GRPC-QUICKSTART to the left of the cursor and then after running the command certs, as shown below. For the password use the one-time password that you used for generating the SDK credentials.

Your key.pem file should look like below. If you do not see Proc-Type: 4,ENCEYPTED on line 2, you have successfully decrypted key.pem.

4. Replace YOUR_EMAIL_ADDRESS@EMAIL.COM in main.go on line 29 with your email address in order to receive the welcome email with card url which your member will also receive.

5. Check the API region of your account here and change it accordingly, for Europe/Pub1 use gRPCHost = "grpc.pub1.passkit.io" and for USA/Pub2 use gRPCHost = "grpc.pub2.passkit.io".

6. Go back to root directory with cd ../. Then run go mod tidy , then go run main.go to create a sample membership card, coupon card and boarding pass (with default templates & tiers/offers) and issue them. If you are in your root directory the terminal should show PASSKIT-GOLANG-GRPC-QUICKSTART to the left of the cursor.
