Purpose and usage

What this endpoint does

Bind an accessible top-level Data Vault folder in a dedicated workspace at an expected version. Gateway re-resolves folder and workspace authority.

When to use it

Use after an administrator selects an existing top-level listing folder in a dedicated workspace.

OUTCOME · Create or advance

What changes

Retains a versioned folder reference and audit event. It never moves, shares or publishes documents.

WHY IT MATTERS

Gives people and agents a contract-backed way to advance bind listing folder.
Connects private issuer preparation to public, citation-bearing disclosure without exposing draft evidence or collapsing review, signature, finality, and availability into one state.

ISOLATION + AUTHORITY

Workspace, issuer, offering, security-class draft, Data Vault object version, requirement pack, diligence case, evidence view, reviewer decision, auditor attestation, release, signer, validator finality, replication, public index, and investor eligibility remain distinct. Launchpad cannot issue, mint, custody, sell, trade, match, settle, or authorize an investment, and its public routes expose only finalized disclosure evidence.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required offering_id (path), folder_id (body), expected_version (body) exactly as defined by the live contract.
Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
Resolve the authenticated workspace and derived issuer, reviewer, auditor, signer, or publisher authority for this stage; use exact Data Vault versions and distinguish private preparation from finalized public disclosure.

WHAT TO DO NEXT

Re-read bind listing folder using the canonical identifier returned by this operation.
Reconcile an ambiguous response with the same idempotency key before attempting another mutation.
Follow returned canonical identifiers and commitments into the next explicit Launchpad stage, re-attesting protected evidence and re-reading release finality before public reliance.

AGENT GUIDANCE

Use bind listing folder only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required offering_id (path), folder_id (body), expected_version (body) exactly as defined by the live contract.
Keep draft creation, evidence linking, evidence-view pinning, review, attestation, release assembly, freeze, signature, submission, validator finality, replicated availability, indexing, and supersession as separate lifecycle facts.
After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then re-read bind listing folder using the canonical identifier returned by this operation.
RETRY SAFETY: Do not repeat a successful mutation merely to confirm it. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Persist returned identifiers, versions, commitments, and receipts. Refresh the offering revision, evidence commitments, review and disclosure status, readiness milestone, issuer authority, and publication or finality receipt.

401Bearer credential is missing, expired, or invalid.Authentication required · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY: Retry only with a newly valid credential and fresh replay-protection values. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Assume the outcome is unknown only when the connection failed after transmission; otherwise authentication failed before domain work. Refresh the offering revision, evidence commitments, review and disclosure status, readiness milestone, issuer authority, and publication or finality receipt.
ESCALATE WHEN: Escalate when issuer authority, diligence evidence, disclosures, approvals, publication, or chain finality cannot be matched to one immutable revision.

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY: Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION: Confirm the caller and resource resolve to the same authority boundary for issuer-private offerings, evidence, reviews, disclosures, readiness milestones, publication, and finality receipts.
ESCALATE WHEN: Escalate when issuer authority, diligence evidence, disclosures, approvals, publication, or chain finality cannot be matched to one immutable revision.

CALLER ACTION: Rebuild the request from the live OpenAPI operation and correct the rejected method, media type, header, parameter, or body field.
RETRY SAFETY: Do not retry the same invalid request. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Compare the submitted values with the documented constraints before another call. Refresh the offering revision, evidence commitments, review and disclosure status, readiness milestone, issuer authority, and publication or finality receipt.
ESCALATE WHEN: Escalate when issuer authority, diligence evidence, disclosures, approvals, publication, or chain finality cannot be matched to one immutable revision.

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Preserve the exact request and treat the outcome as uncertain until authoritative state proves whether it committed.
RETRY SAFETY: Reconcile before retrying. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions. Use bounded backoff with jitter.
STATE RECONCILIATION: Refresh the offering revision, evidence commitments, review and disclosure status, readiness milestone, issuer authority, and publication or finality receipt.
ESCALATE WHEN: Escalate when issuer authority, diligence evidence, disclosures, approvals, publication, or chain finality cannot be matched to one immutable revision.

OPERATIONAL NOTES

Security and lifecycle guarantees

Bind an accessible top-level Data Vault folder in a dedicated workspace at an expected version. Gateway re-resolves folder and workspace authority.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
Mutations are retry-safe only when the same Idempotency-Key and canonical request body are reused.
The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.

Reference version and availability details

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-10-02T23:27:55.510Z. Authentication, tenant, feature, venue, and market policy still apply.
