Introduction

This repository contains the code for the Questbook API endpoint (https://api.questbook.app) built using the Serverless framework. There are two types of endpoints:

1. /zapier/v1/:chain/:event - Designed specifically for the Questbook Zapier App.
2. /mappings/:event - Used to map email IDs to in-app wallet addresses.

How to Run Locally

1. Clone the repository.
2. Run yarn to install all the packages.
3. Run sls offline and wait for the TypeScript to compile.
4. The API is ready to be tested.

How to deploy to Serverless

1. Make sure you have the AWS Credentials set
2. Run sls deploy

Endpoint Information

/zapier/v1/:chain/:event

• chain: Can take up values 5 (Goerli), 42220 (Celo), 137 (Polygon), or 10 (Optimism). It specifies which subgraph to query. Any other value would return an error.
• event: Can take the following values:
  • ProposalSubmitted: Queries the subgraph to list proposals submitted in the last 24 hours.
  • ProposalUpdated: Queries the subgraph to list proposals updated in the last 24 hours.
  • PayoutStatus: Queries the subgraph to list fund transfers initiated or updated in the last 24 hours.
  • ReviewerSubmittedReview: Queries the subgraph to list reviews submitted in the last 24 hours.

/mappings/:event

• event: Can be either check or create.
  • check: Confirms if there exists a mapping from an in-app wallet address to any email address.
  • create: Inserts a new mapping into the database if a mapping does not exist.

How to Add a New Endpoint/Event for Zapier Integration

1. Under src/graphql, create a new .graphql file describing the query to be executed upon calling the endpoint.
2. Run yarn generate. The src/generated/graphql.ts file should be modified to contain the types for the above query.
3. Add the relevant type string for the new event in src/types/index.ts.
4. Inside functions/zapier, create a new .ts file with the name of the event.
5. Check the formatting of the data received in the request body inside the .ts file, and call the function work defined in src/utils/work.ts.
6. Modify two files:
   1. In src/utils/fetchData.ts, add the case for the newly introduced event in the switch-case block and specify the Apollo.DocumentNode to be called for the new event. Import the Apollo.DocumentNode from src/generated/graphql.ts. It should be the same one generated in step 2.
   2. In src/utils/dataFormat.ts, modify the switch-case block in a similar fashion to specify the formatting function to be applied to the data returned by the query specified in the above step.
7. You are good to go.

Tip: If you receive a response like {'error': {}} upon querying an endpoint, check the formatting function. You might be trying to access non-existent items in the query.

About the .env File

TABLE_NAME=<Name of the AWS Dynamo DB Table that stores the mappings>
INFURA_ID=<ID of the Infura App. Needed when decoding the transaction while creating a new mapping>
