Straddle Plan

Purpose

Run a guided conversation (5-8 questions) that produces a complete Straddle integration plan. The plan covers entity mapping, API flows, code examples, webhook handlers, and compliance notes -- all tailored to the developer's specific use case and SDK language.

The plan is the artifact the developer uses to build their sandbox integration.

Scope boundaries

• Execute API calls -> use sandbox-test
• Answer ad-hoc integration questions -> use straddle-integrate
• Set up MCP/CLI/keys -> use setup
• Explain statuses -> use explain-status

Point users to the appropriate skill if they ask for something outside scope.

Reference files

Read before generating each plan section. Shared with straddle-integrate:

| Topic | Reference | |-------|-----------| | Entities, statuses, webhooks, ACH | | | Embed: onboarding, accounts, headers | | | Pay by Bank: customer, bridge, payments | | | SDKs, Bridge Widget, errors | |

Doc search enforcement

Reference files contain stable structural and behavioral knowledge. Enumerated factual lists (return codes, event names, numeric limits) have been replaced with links to authoritative documentation pages.

Doc search tools:

• search_docs MCP tool -- SDK and API reference (method signatures, parameters, code examples). Always pass language param.
• Product docs -- search by POSTing to https://docs.straddle.com/mcp with {"jsonrpc":"2.0","method":"tools/call","params":{"name":"search_straddle_docs","arguments":{"query":"YOUR_QUERY"}},"id":1} and header Accept: application/json, text/event-stream. Returns payment guides, compliance, sandbox testing.

Default to search_docs for any code or API question.

For EACH section of the output plan:

1. Read the relevant reference file for structural baseline
2. Follow all documentation links in the reference file for current values
3. Use search_docs (pass language param) for method signatures and code examples
4. Search product docs (POST to https://docs.straddle.com/mcp) for current guides and compliance info
5. Compare all sources. MCP results win on conflicts (they are live). Flag discrepancies.

Never generate a plan section from reference files alone. Never guess at enumerated values -- always search or follow the doc links.

Documentation index: https://docs.straddle.com/llms.txt -- complete sitemap of all Straddle documentation pages. Use as a fallback when MCP search doesn't return the needed content.

Conversation flow

Ask questions one at a time. Skip conditional questions when they don't apply.

Step 0: Prerequisites

Recommend (do not gate):

> Before we start, two things that help: > > Straddle CLI -- full API access from your terminal: > `` > brew install straddleio/tools/straddle > export STRADDLE_API_KEY=your_sandbox_key > `` > > API key from the Straddle Dashboard.

Proceed to step 1 immediately.

Step 1: Use case

> What are you building? > 1. A single business that needs to collect or send bank payments > 2. A SaaS product where your clients need payment capabilities > 3. A marketplace connecting buyers with sellers

Store as use_case: account, saas, or marketplace.

Step 2: SDK language

> Which language is your backend? > 1. TypeScript / Node.js > 2. Python > 3. Go > 4. Ruby > 5. C# / .NET > 6. Raw HTTP

Store as sdk_language. Map to search_docs language param: typescript, python, go, ruby, http. For C#, the search_docs tool does not have a csharp option -- use http for raw API shapes and supplement with typescript examples (the C# SDK follows the same patterns).

After answer, recommend the SDK install command from .

Step 3: Business context

> Describe your business in 1-2 sentences. What do you do, who are your users, and what payments need to happen?

Free text. Drives entity mapping.

Step 4: Payment directions

> What payment directions do you need? > 1. Charges only -- pull money from bank accounts > 2. Payouts only -- push money to bank accounts > 3. Both

Step 5: Customer types

> Who are you transacting with? > 1. Individuals (consumers, people) > 2. Businesses (companies, vendors, contractors) > 3. Both

Step 6 (saas/marketplace only): Scale

> Roughly how many merchants/sellers at launch?

Skip for account use case.

Step 7: Existing bank linking

> Do you already have a bank linking provider? > 1. Yes, Plaid > 2. Yes, Quiltt > 3. No, starting fresh > 4. Not sure

"No" and "Not sure" -> recommend Bridge widget.

Plan generation

After all questions, announce:

> Generating your integration plan. Cross-referencing Straddle docs and SDK reference for [language].

Generate each section below. Follow doc search enforcement for every section. Use the developer's business terms (from step 3) throughout.

Section 1: Entity mapping

Table mapping their domain concepts to Straddle entities.

• account: their business = account holder, their customers = Customer, bank links = Paykey
• saas/marketplace: their platform = Platform, their merchants = Account (hosted onboarding), their end-users = Customer, bank links = Paykey

Section 2: Onboarding flow

• account: "Not applicable -- account set up via Dashboard."
• saas/marketplace: Hosted onboarding form. Search SDK docs for embed component. Show code. Explain platform.id, env, external.id. Document status flow: created -> onboarding -> active.

Section 3: Customer and paykey flow

Search SDK docs for customers.create and Bridge setup.

• Create customer with required fields
• Verification by type: individual (always reviewed), business without complianceprofile (auto-verified, no B2B chargeback protection), business with complianceprofile (standard)
• Customers in review can proceed (items held until cleared)
• Bank connection based on step 7: Bridge (@straddlecom/bridge-react or bridge-js), Plaid token, or Quiltt token
• Paykey creation statuses: active, review, rejected
• Verify with CLI: straddle customers get --format json, straddle paykeys list --format json

Section 4: Payment flow

Search SDK docs for charges.create / payouts.create.

• Code examples for applicable payment directions
• Straddle-Account-Id header rules per use case (read from embed.md header table)
• Consent type: internet for individual, signed for B2B
• Authorization guides: https://help.straddle.com/article/authorization-guide, https://help.straddle.com/article/b2b-agreements
• Balance check modes: enabled (default), required (high-value), disabled (future-dated/manual-entry)
• Test with CLI before writing SDK code: straddle charges create --help to see required fields, straddle charges get --debug to inspect responses

Section 5: Webhook handler

Search product docs for webhook events and security.

• Events filtered by use case + payment directions
• Status transitions per event (from domain.md lifecycle)
• Terminal status guard with timestamp ordering
• on_hold: system holds (Dashboard) vs user holds (release via API)
• Signature verification
• Idempotency: store webhook-id, dedup on replay

Section 6: Sandbox testing

Search product docs for sandbox guide.

• sandbox_outcomes for test scenarios
• simulate for account onboarding (saas/marketplace)
• CLI commands for verifying sandbox state:
• straddle customers list --environment sandbox --format json
• straddle charges get --environment sandbox --debug
• straddle paykeys list --environment sandbox --format json
• Use --help on any command to see available parameters
• Link: https://docs.straddle.com/guides/resources/sandbox-paybybank

Section 7: Pre-Production Checklist

• Idempotency-Key on all POST/PATCH (10-40 chars)
• Webhook signature verification
• Error handling: error.type, error.items[].reference, log api_request_id
• NACHA compliance: consent records, notification emails
• Retry on 429 (no inherent rate limits)
• Address note: account uses line1/postal_code, customer uses address1/zip (known, will be unified)
• Use straddle --debug to troubleshoot unexpected API responses

Delivering the plan

Present the full plan in conversation. Then offer:

> Save this plan to straddle-integration-plan.md?

Revising the plan:

To revise a section, ask about it. There is no need to restart the full conversation. Re-read the relevant reference files and re-search docs for the updated sections only.

Next steps:

> 1. Review the plan -- ask questions or request changes to any section > 2. Test in sandbox -- try /sandbox-test for guided testing > 3. Explore the Straddle docs for deep dives
