Dotloop API
Dotloop is a real estate transaction management platform that replaces separate form creation, e-signature, and transaction-tracking systems with a single end-to-end solution. This page is an independent design exercise that asks what a well-designed Dotloop API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.
This page is an independent analysis by Supergood of what a well-designed Dotloop API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing Dotloop product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
What is Dotloop?
Dotloop is a real estate transaction management platform that replaces separate form creation, e-signature, and transaction-tracking systems with a single end-to-end solution. Agents, teams, and brokerages use Dotloop to build and edit documents, collect legally binding e-signatures, organize every deal as a "loop," communicate with clients over email, SMS, or fax, and give office leaders real-time visibility into transaction status across the brokerage.
Core product areas include:
- Interactive document editor with customizable forms and templates
- Legally binding e-signatures and document sharing
- Loops (transactions) with folders, tasks, and activity tracking
- Contact directory and client communication (email, SMS, fax)
- Broker dashboards with real-time transaction visibility and reporting
- Public API v2 and 75+ partner integrations across CRM, back office, and marketing
An API for a platform like this would naturally organize around its core data entities:
- Profiles (individual agent and brokerage accounts)
- Loops, Loop Details, and Loop Templates
- Folders and Documents
- Participants and Contacts
- Tasks, Task Lists, and Activities
- Webhook subscriptions and events
The Dotloop Integration Challenge
Dotloop publishes a documented Public API v2, but turning it into reliable production automation across many brokerages still takes real work:
- Partner registration gate: API access requires registering at info.dotloop.com/developers to receive a client ID and secret before any integration can run
- OAuth 2.0 token lifecycle: Access tokens expire roughly every 12 hours and must be refreshed proactively or lazily on a 401, which headless jobs often mishandle
- Deeply nested resource paths: Documents and folders live under /profile/:id/loop/:loop_id/folder/:folder_id, so callers must walk profile → loop → folder hierarchies for most operations
- Rate limits: 100 requests per minute per client per user, with 429s and X-RateLimit headers that batch and sync jobs must respect
- Per-brokerage customization: Loop templates, form sets, and task lists vary by office, so a single hard-coded mapping breaks across accounts
- Webhook plumbing: Subscriptions deliver HTTPS POST payloads with HMAC-SHA1 signatures and retry semantics that you must verify, dedupe, and persist
What a Dotloop API Could Look Like
If Dotloop exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
- First-class authentication: session handling with support for MFA and enterprise sign-on where the platform uses them
- Consistent resources: normalized JSON schemas and pagination across the platform's core objects
- Reliable writes: idempotency keys and validation that mirrors the platform's own workflow rules
- Entitlement awareness: endpoints scoped to what each customer's licensing actually permits
The endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

Potential API Endpoints
Authentication
/authenticateWould authenticate via OAuth 2.0 using your client ID and secret, exchange the authorization grant, and obtain a Bearer access token for downstream calls.
Profiles
/profilesWould list the agent and brokerage profiles accessible to the authenticated account, or retrieve an individual profile by id.
Loops
/loopsWould list loops (transactions) for a profile with filters for status, transaction type, and update time, or retrieve a single loop's details.
Loops
/create_loopWould create a new loop with the Loop-It facade, populating transaction details, participants, and contacts in a single call.
Documents
/documentsWould list and download documents within a loop's folders, walking the profile, loop, and folder hierarchy.
Contacts
/create_contactWould create or update contacts in the directory and keep them synced across integrated CRM and back-office tools.
Use Cases
Sync transactions into your CRM and back office
- Pull loops, loop details, and statuses from each brokerage profile into a single warehouse - Stream participant and contact changes to keep CRM records in sync - Surface closing dates and milestones to reporting and commission systems
Automate loop creation from external systems
- Use Loop-It to create a new transaction directly from your CRM or lead source - Pre-populate participants, contacts, and transaction details on creation - Apply the brokerage's loop template so forms and tasks are ready on day one
Centralize documents and e-signature status
- Pull executed documents and folder contents from every loop for archival - Track document and signature completion across active transactions - Push final closing packages into a document management or accounting system
React to transaction events in real time
- Subscribe to webhook events for loop creation, updates, and participant changes - Verify HMAC-SHA1 signatures and dedupe deliveries before processing - Trigger downstream automations like compliance reviews and back-office tasks
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require OAuth 2.0 with client ID/secret and Bearer access tokens, refreshed automatically in a managed session
Connectivity
Would build on dotloop Public API v2 at api-gateway.dotloop.com/public/v2 plus authenticated app surfaces where needed
Response format
Normalized JSON across profiles, loops, folders, documents, participants, and contacts
Rate limits
Adaptive throttling within Dotloop's 100 requests/minute per client per user limit, honoring X-RateLimit headers
Session management
Would need automatic 12-hour token refresh, 401 recovery, and credential rotation
Data freshness
Near real-time pulls for loops, documents, and contacts with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access tokens, SOC 2-aligned controls, and audit logging
Webhooks
Subscription-based HTTPS callbacks with HMAC-SHA1 signature verification for loop, participant, and contact events
Latency
Design target: sub-second reads on cached entities; multi-second writes when creating loops and uploading documents
Throughput
Design target: horizontally scaled workers sized to brokerage-wide loop and document volume across many profiles
Reliability
Retry, backoff, and idempotency handling for loop creation, document, and contact writes
Versioning
Clear versioning and change management would matter as Dotloop evolves
Frequently asked questions
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.
