CONNECTOR OVERVIEW ## Overview The Dropbox Sign connector gives SaaS product teams programmatic access to signature requests, templates, embedded signing and account features. Use Cyclr to orchestrate multi-step workflows, capture signed documents, and deliver customer-facing signing flows inside your application without building each integration from scratch. ### Why use Cyclr? Cyclr lets engineering and product teams compose, govern and publish Dropbox Sign automations as customer-facing integrations. Ship white-label integrations, centralize credentials and build MCP tools that expose selected Dropbox Sign methods to end customers. PRODUCT USE CASES ## Use cases Create in-app signing flows, automate document delivery and downloads, embed template editors, and publish governed integrations to your customers via Cyclr’s embedded marketplace. ### In-app contract sending and signing Allow users to generate and send contracts from your app, track signer status and download final signed PDFs automatically. ### Embedded onboarding forms and agreements Embed signing flows and template editors so customers sign onboarding documents without leaving your product. ### Automated approvals and bulk sends Automate bulk signature distribution and reminders for invoices, NDAs and regulatory documents across tenants. ORCHESTRATION ## How Dropbox Sign works with Cyclr Cyclr sits between your SaaS product and Dropbox Sign to handle authentication, govern access and orchestrate every API call per customer, at scale. 1. 1 ### Your SaaS product Your app requests an action for a specific customer. 2. 2 ### Cyclr orchestration Cyclr authenticates, applies policies and routes the request. 3. 3 ### Dropbox Sign Dropbox Sign processes the request and returns a response to your app. Customer-specific authentication · Governed data movement · Centralized visibility and audit CONNECTOR COVERAGE ## Available connector capabilities Explore Dropbox Sign methods you can orchestrate through Cyclr. Search connector methods INTEGRATIONS + MCP TOOLS ### Use any Dropbox Sign method in an integration or as an MCP tool Every available connector method can be added to an integration workflow built with Cyclr or exposed as a governed MCP tool. Use the same multi-tenant authentication, orchestration and governance layer to deliver customer-facing integrations and AI-agent capabilities inside your SaaS product.

Responses include list_info with page, page_size, num_pages and num_results. #### Rate limits Standard endpoints ~100 requests per minute; higher-tier document endpoints ~25 per minute; test mode ~10 per minute. Rate headers and 429 responses provided. IMPLEMENTATION ## Authentication at a glance Supports account API keys via HTTP Basic auth and OAuth access tokens (Bearer). API key is used as Basic username with empty password; OAuth tokens go in Authorization header. Authentication methodAPI key (Basic) or OAuth 2.0 (Bearer)Credential required Account API key or OAuth client_id and client_secret; callback URL for API apps. **Before you begin:** Embedded or OAuth apps may require Dropbox Sign app approval or self-publish before production. [View setup guide](https://docs.cyclr.com) AI INTEROPERABILITY ## Use Dropbox Sign methods in MCP servers Cyclr can expose any available Dropbox Sign connector method as a governed MCP tool. - Expose connector methods as MCP tools - Combine them with your product data and other connectors - Apply tenant-aware access and governance - Orchestrate end-to-end MCP-triggered workflows [Explore MCP PaaS](https://cyclr.com/product/mcp-paas/) COMMON QUESTIONS ## Frequently asked questions Which authentication methods does the Dropbox Sign connector support? *↓* Dropbox Sign supports account API keys (HTTP Basic with key as username) and OAuth access tokens (Bearer). Cyclr can store either credential type and use them per-tenant. Can I embed Dropbox Sign signing flows inside my application? *↓* Yes. Dropbox Sign supports embedded signing and embedded templates. Embedded and OAuth workflows may require app approval or self-publishing before production. How does Dropbox Sign deliver webhook events and how should I verify them? *↓* Events are sent as multipart/form-data with a json field. Use the event_hash or Content-Sha256 and IP whitelist to verify callbacks; Dropbox Sign requires HTTPS for callbacks. What rate limits should I design for when using Dropbox Sign? *↓* Design for ~100 requests per minute for standard endpoints, ~25 per minute for document-heavy endpoints and ~10 per minute in test mode. Honor X-Ratelimit-* headers and handle 429 responses.
