This repository contains the AWS Lambda based handler for Prismic.io webhooks that are run whenever the content is changed in Prismic. Handy for building/publishing content using AWS Services.

• Install Node 6.10 (usage of NVM or n highly suggested!)
• Install Serverless 1.12: npm i -g serverless@1.12 (likely to work with newer versions, too)
• Clone this repo: git clone https://github.com/juhamust/prismic-lambda-webhook.git
• Install dependencies: cd prismic-lambda-webhook && npm install -D
• Run the tests (optional): npm test
• Set valid values in env.yml (or create copy like local.yml and use --env=local while running commands). NOTE: API token is only needed if you want to use the actual sns -based handler example

  PRISMIC_API_ENDPOINT: https://my-repo.prismic.io/api
  PRISMIC_API_TOKEN: see-prismic-api-settings
  PRISMIC_WEBHOOK_SECRET: my-secret

• Deploy the service: sls deploy --profile=myawsprofile
• Copy the generated endpoint and your PRISMIC_WEBHOOK_SECRET and place them into Prismic.io Webhook settings
• Tryout the trigger: It should be successfull. Check also AWS CloudWatch logs.

Sequence in short:

1. User changes content in Prismic.io service
2. Prismic triggers the webhook into address defined in settings.
3. Webhook is handled (and authorized) by simple AWS Lambda based endpoint
4. Lambda triggers SNS message with topic: PRISMIC_LAMBDA_WEBHOOK
5. Another service/lambda/whatever in AWS is triggered by the SNS (see serverless.yml and build.js for example)

• Added Prismic.io build example
• Improved Serverless settings/options

• Initial release
