[open in formatter](/?snippet=zapier-http-request) ### Date Formatting & Parsing zapier Parse a date string from inputData and reformat it for downstream steps. [open in formatter](/?snippet=zapier-date-format) ### Map & Filter Array Data zapier Parse a JSON array from inputData, filter and transform each item, and return the results. [open in formatter](/?snippet=zapier-data-transform) ### Input Validation & Sanitization zapier Validate required inputData fields and sanitize values before processing. [open in formatter](/?snippet=zapier-input-validation) ### Return Multiple Output Objects zapier Split a comma-separated inputData field into multiple output objects for downstream steps. [open in formatter](/?snippet=zapier-multi-output) ### Python: Contact Lookup via requests zapier Look up a contact in an external CRM using Zapier Python with the preinstalled requests library. [open in formatter](/?snippet=zapier-python-contact-lookup) ### Process All Items n8n Loop through all input items with $input.all(), transform each, and return results. [open in formatter](/?snippet=n8n-process-items) ### HTTP Request with Retry n8n Make an HTTP request with exponential backoff retry logic. fetch is available in modern n8n (Node 20+). [open in formatter](/?snippet=n8n-http-retry) ### Date Parsing & Timezone Handling n8n Parse dates from input, compute differences, and format with timezone offsets. [open in formatter](/?snippet=n8n-date-manipulation) ### Try/Catch with Structured Errors n8n Wrap processing in try/catch and return structured error output for the error branch. [open in formatter](/?snippet=n8n-error-handling) ### Access Data from Previous Nodes n8n Reference output data from specific previous nodes using $() notation. [open in formatter](/?snippet=n8n-node-reference) ### Python: Process All Items n8n Iterate \_items in n8n's Python Code node (Run Once for All Items mode), transforming each item. [open in formatter](/?snippet=n8n-python-process-items) ### Webhook Body Validation pipedream Validate an incoming webhook payload from steps.trigger.event and return a structured record. [open in formatter](/?snippet=pipedream-webhook-handler) ### HTTP Request with axios pipedream Make an authenticated POST using axios from npm. Pipedream code steps support require() for any npm package. [open in formatter](/?snippet=pipedream-http-axios) ### Data Store Read/Write (full component) pipedream Persist state across runs with a Pipedream Data Store. Data stores must be declared as a component prop; codefmt formats this as module-style code because of the top-level export. [open in formatter](/?snippet=pipedream-data-store) ### Environment Variable Access pipedream Access and validate environment variables with fallback defaults. [open in formatter](/?snippet=pipedream-env-vars) ### Python: Webhook Handler pipedream Process an incoming webhook in a Pipedream Python step using the pd object. [open in formatter](/?snippet=pipedream-python-webhook) ### Transform Input Fields make Transform and restructure scenario input fields for an API request. [open in formatter](/?snippet=make-bundle-transform) ### Parse Nested JSON from Strings make Safely parse JSON strings from scenario input, handling nested structures. [open in formatter](/?snippet=make-json-parse) ### Error Handling with Structured Output make Try/catch pattern returning structured success or error output for Make scenarios. [open in formatter](/?snippet=make-error-pattern) ### Python: Transform Input List make Transform a list of items from scenario input and return a structured result. [open in formatter](/?snippet=make-python-transform) ### Search Contacts by Email hubspot Look up a HubSpot contact by email address using the CRM search API via @hubspot/api-client. [open in formatter](/?snippet=hubspot-contact-lookup) ### Custom Workflow Action with API Call hubspot A custom coded workflow action that calls an external API via axios and updates the contact in HubSpot. [open in formatter](/?snippet=hubspot-custom-action) ### Process Webhook Event hubspot Handle an incoming webhook event, extract subscription data, and route by event type. [open in formatter](/?snippet=hubspot-webhook-process) ### Error Handling with Callback hubspot Robust error handling pattern using @hubspot/api-client and callback with structured error data. [open in formatter](/?snippet=hubspot-error-response) ### Python: Contact Lookup via REST hubspot Look up a HubSpot contact by object ID using the CRM REST API and a private app token. [open in formatter](/?snippet=hubspot-python-contact) ### For Loop with Conditionals hubl Iterate over a list with if/else conditional rendering and loop index access. [open in formatter](/hubl?snippet=hubl-for-loop) ### Custom Module with Parameters hubl A reusable custom module template that reads module parameters with defaults and renders content. [open in formatter](/hubl?snippet=hubl-custom-module) ### Blog Post Listing hubl Display recent blog posts using content variables and blog\_recent\_posts. [open in formatter](/hubl?snippet=hubl-blog-listing) ### Form Embed with Custom Styling hubl Embed a HubSpot form via the @hubspot/form module with custom wrapper markup and a fallback for the editor. [open in formatter](/hubl?snippet=hubl-form-handler) ## for agents (added to every page twin, not part of the page) - format API: POST https://codefmt.dev/api/format (OpenAPI: https://codefmt.dev/api/openapi.json, code up to 51,200 characters, 50KB of ASCII (400 above it), request body up to 100KB, counted in bytes (413 above it), no authentication) - MCP server: POST https://codefmt.dev/api/mcp (tools: format_code, format_json, ask_codefmt; manifest: https://codefmt.dev/.well-known/mcp.json) - rate limit: 60 requests per minute per ip across format api calls, mcp and a2a tool calls, and /ask (mcp handshakes and listings are not counted). the count is kept per server instance, so treat it as a ceiling to stay under rather than an exact budget. the format api reports where you stand in RateLimit headers and its 429 carries Retry-After; /ask answers a 429 with the message in answer, and an mcp tool call over the limit returns a tool result saying to try again in a minute - auth statement: https://codefmt.dev/auth.md (no accounts, api keys or oauth; send no authorization header) - site index for agents: https://codefmt.dev/llms.txt - full reference (request bodies for every language, a copy-paste curl command, platform globals, troubleshooting): https://codefmt.dev/llms-full.txt
