Caspio 73.0
Jul 02, 2026 • 4 minutes to readRelease Notes
Introducing REST API v4
REST API v4 is the next evolution of the Caspio REST API and a major, deliberate investment in the platform you already build on. It expands coverage, improves efficiency, and adds new capabilities for developers and AI-powered applications, while building on everything you know from v3. Your existing v3 integrations continue to work exactly as they do today, so you can adopt v4 on your own schedule.
What v4 brings:
- More from every call — Create, update, delete, and process records in bulk with predictable responses, including returned IDs, partial-failure reporting, and consistent pagination for all list responses.
- AI-ready by design — Embedded AI guidance, API discovery endpoints, centralized AI context, and actionable error diagnostics with profile-awareness.
- Discover your apps and schema — Discover all tables, views, directories, and webhooks in a single call, now with relationships, triggered actions, and Flex or Bridge usage..
- Built-in safety guardrails — Bulk updates and deletes include safeguards that prevent unintended large-scale changes, requiring explicit conditions to avoid unscoped mass operations.
- Integrations that don’t break — Objects are addressed by stable IDs instead of names, so renaming a table or view never breaks your integration.
- Errors that explain themselves — Every error includes a machine-readable code, a request ID for support, fix hints, and a documentation link.
- Access records by ID — Read, update, or delete a single record by its ID across tables, views, and directory users. No WHERE clauses, and no risk of touching more records than intended.
- Performance and scale — Faster responses, improved support for large workloads, and clearer visibility into usage limits.
- Security and access — The same strong protection as v3, including OAuth 2.0 authentication and granular, least-privilege API profile permissions.
Redesigned API Profile Management
Setting up and managing API access is now faster and easier. API Profiles have a new home under Integrations, with a streamlined experience that guides you through setup and keeps credentials, permissions, and access controls organized in one place. This release also adds:
- Granular permissions — Set default permissions by object type and override them for specific objects to support least-privilege access.
- Generate bearer tokens directly from the profile — Generate a bearer token directly from the UI and test API calls immediately in Swagger UI without leaving Caspio.
- Expanded IP access control — Support for IPv6 addresses and IP address ranges.

Enhancements to Flex
Flex is our next-generation framework for building modern cloud applications.
Theme Editor for Apps – Customize application themes directly within Segments, with live preview support before applying changes. Save custom themes and reuse them across multiple segments and apps for a consistent look and feel.
Enhanced Date/Time Form Elements – Date/Time form elements now support minute-level offsets for minimum and maximum date boundaries. You can also define fixed daily time windows using Min Time and Max Time settings which are enforced independently of the selected date range.

HMAC-SHA256 Signature for Webhooks
Every outgoing webhook now includes an HMAC-SHA256 signature to verify that the request originates from Caspio and has not been modified in transit. Receivers that do not use the new headers are unaffected, and for systems that cannot compute an HMAC, an optional compatibility mode can include the signing secret in the payload at the event level.
Learn more about Webhooks.
Enhancements to Vault
You can now create app packages directly from the menu of each Flex application in the application list, making it faster and more convenient to package apps without navigating to Vault.
New IP addresses for Data Import/Export Tasks and Webhooks
Caspio has added new IP addresses for data import/export tasks and webhooks, in addition to the existing ones, to improve speed, scalability, and reliability. If you use an IP allowlist, update it to include the new IP addresses to avoid interruptions to import/export tasks and webhooks.
- For Data Import/Export Tasks, see IP Addresses for Data Import/Export Tasks.
- For Webhooks, see IP Addresses for Webhooks.
Impacted Areas
In this release, Caspio has expanded granular permissions across the REST API, enhancing control and security for API access. These changes impact endpoints in both v2 and v3. Learn more.
Deprecations
Caspio will end support for older AI models in AI-Powered GPT Connect to align the extension with OpenAI’s current models. Learn more.
