Updating a PDA

You can update a PDA by using the updatePDA mutation. Only the issuer of a PDA can update it. You would need the PDA’s id and then the just pass the fields you want to update.

# Query
mutation updatePDA {
  updatePDA(
    input: {
      id: "f34cdbae-7e0b-4527-bb97-08fd0e74effe"
      title: "Update Test 2"
      claim: {
        handleName: "@gateway_xyz" # string
        favoritePosts: ["more awesome"] # array
      }
    }
  ) {
    id
    arweaveUrl
    dataAsset {
      title
      claim
    }
  }
}

You can find an ID of a PDA via 2 ways:

• Calling the getPDAs query

• Finding it in the Data Assets tab in the Gateway Dashboard

Node.js

const axios = require("axios");
let data = JSON.stringify({
  query: `YOUR_GRAPHQL_QUERY_HERE`,
  variables: {},
});

let config = {
  method: "post",
  maxBodyLength: Infinity,
  url: "https://sandbox.protocol.mygateway.xyz/graphql",
  headers: {
    "X-Api-Key": "<YOUR_API_KEY>",
    Authorization: "Bearer <YOUR_AUTHENTICATION_TOKEN>",
    "Content-Type": "application/json",
  },
  data: data,
};

axios
  .request(config)
  .then((response) => {
    console.log(JSON.stringify(response.data));
  })
  .catch((error) => {
    console.log(error);
  });
