It looks like the issue is with how the API key is being passed in the request. In the ConvertKit API, the API key should be included in the query parameters, but it seems like there might be a formatting issue in your code. Here’s a revised version of your component code that should correctly pass the API key and other parameters: import { axios } from "@pipedream/platform"; export default defineComponent({ props: { convertkit: { type: "app", app: "convertkit", }, subscriberId: { type: "string", label: "Subscriber ID", description: "The ID of the subscriber you want to update", }, earningHigh: { type: "string", label: "Earning High", }, earningLow: { type: "string", label: "Earning Low", }, instagram: { type: "string", label: "Instagram", }, }, async run({ steps, $ }) { const url = `https://api.convertkit.com/v3/subscribers/${this.subscriberId}`; const params = { api_key: this.convertkit.$auth.api_key, fields: { EARNING_HIGH: this.earningHigh, EARNING_LOW: this.earningLow, INSTAGRAM: this.instagram, }, }; return await axios($, { method: "PUT", url, params, }); }, }); ### Key Changes: 1. API Key in Params: Ensure the api_key is included in the params object. The api_secret is typically not required for this type of request, so it has been removed. 2. URL Formatting: Ensure the URL is correctly formatted without angle brackets. This should resolve the “API Key not present” error. If you continue to experience issues, please double-check that your API key is correctly set in the Pipedream app configuration for ConvertKit.
