How to automate Sinch user provisioning, and what it actually costs

Summary and recommendation

Sinch, the communications platform and API provider, does not offer publicly documented SCIM provisioning on any plan. While Sinch supports SAML 2.0 SSO through their Sinch ID system for dashboard access, user provisioning remains a manual process. This creates a significant operational burden for IT teams managing developer and operations users across Sinch's various communication APIs and services, especially in organizations where team composition changes frequently as projects scale up or wind down.

The lack of automated provisioning becomes particularly problematic for companies using Sinch's enterprise communications APIs, where access control is critical for both security and cost management. Without SCIM, IT teams must manually create, update, and deactivate user accounts, creating compliance risks and operational overhead. SSO alone doesn't solve this problem—it only handles authentication for existing accounts, leaving the entire user lifecycle management process as a manual task.

The strategic alternative

Sinch has no native SCIM. Automate offboarding, user access reviews, and license workflows across every app, including the ones without APIs. We maintain the integration layer underneath. You focus on judgment, not plumbing.

The cost of not automating

Without SCIM (or an alternative like Stitchflow), your IT team manages Sinch accounts manually. Here's what that costs:

The Sinch pricing problem

Sinch gates SCIM provisioning behind premium plans, forcing significant cost increases for basic user management.

What this means in practice

Without SCIM provisioning, IT teams must manually create and manage user accounts in Sinch's dashboard:

New hires
Manual account creation required before SSO can work
Role changes
Manual permission updates for developers moving between projects
Offboarding
No automated account deactivation when employees leave
Audit compliance
Manual user access reviews across all Sinch projects

For development teams using Sinch APIs across multiple applications, this creates significant administrative overhead as user access must be managed separately from your identity provider.

Additional constraints

Domain configuration required
SSO setup requires domain verification and configuration through Sinch ID
Limited IdP support
Only supports generic SAML, Okta, and Azure AD - no Google Workspace or OneLogin integration
API key management
Separate process for managing API keys used by applications
No JIT provisioning
Users must be pre-created before they can authenticate via SSO

Summary of challenges

  • Sinch does not provide native SCIM at any price tier
  • Organizations must rely on third-party tools or manual provisioning
  • Our research shows teams manually provisioning this app spend significant hidden costs annually

What Sinch actually offers for identity

SAML SSO (Enterprise)

Sinch provides SAML 2.0 authentication through their Sinch ID platform:

SettingDetails
ProtocolSAML 2.0
Supported IdPsOkta, Azure AD/Entra, custom SAML providers
ConfigurationDomain-based setup via Sinch ID dashboard
ProvisioningManual account creation required

The reality: Sinch's SSO is limited to dashboard authentication. As a Communications Platform as a Service (CPaaS), most user interaction happens through APIs rather than the web dashboard, making SSO less critical than for traditional SaaS applications.

No SCIM Provisioning

FeatureAvailable?

Update users❌ No
Deactivate users❌ No
Group sync❌ No
JIT provisioning❌ No

Sinch has no publicly documented SCIM endpoint or provisioning capabilities. For a communications API platform where most access is programmatic rather than user-based, this creates challenges for organizations that need to manage developer and operations team access at scale.

Why this matters: Communications platforms still require user lifecycle management for dashboard access, API key management, and role-based permissions. Without SCIM, IT teams must manually provision and deprovision access to Sinch's management interfaces.

What IT admins are saying

Sinch's lack of automated provisioning forces IT teams into manual user management workflows:

  • No documented SCIM support despite enterprise positioning
  • Manual user provisioning required for all Sinch ID accounts
  • SSO works but doesn't eliminate the account creation overhead
  • Communications platform complexity without identity management automation

The recurring theme

Sinch provides enterprise SSO through Sinch ID but leaves IT teams manually managing user lifecycles. For a communications platform that could have hundreds of developer and operations users, this creates significant administrative overhead.

The decision

Your SituationRecommendation
Small dev team (<10 users) using Sinch APIsManual user management is workable
Developer-focused team with stable membershipRely on SAML SSO for authentication only
Enterprise with 25+ developers/operatorsUse Stitchflow: SCIM not publicly available
Multi-team organization with frequent onboardingUse Stitchflow: automation essential for scale
Compliance-heavy environment requiring audit trailsUse Stitchflow: manual provisioning creates compliance gaps

The bottom line

Sinch provides robust communications APIs with SAML SSO, but offers no documented SCIM provisioning capabilities. For organizations that need automated user lifecycle management beyond basic authentication, Stitchflow delivers the provisioning automation that Sinch doesn't provide.

Communications / CPaaS

ProvisioningNot Supported
Manual Cost$11,754/yr

Telnyx, the communications platform for voice, SMS, and SIP trunking, does not offer SCIM provisioning on any plan. While Telnyx provides SAML 2.0 SSO integration with Azure AD and other SAML providers through their Mission Control Portal, this only handles authentication, not user lifecycle management. IT teams must manually create, update, and deactivate user accounts in Telnyx's Mission Control Portal, even when SSO is configured. This creates a significant operational burden for organizations using Telnyx's communications services. Without automated provisioning, IT teams cannot enforce consistent access policies across their telecom infrastructure, and departing employees may retain access to voice and messaging capabilities longer than intended. For a communications platform that handles sensitive customer interactions and potentially expensive usage-based billing, manual user management introduces both security and cost control risks.

B2B Revenue Intelligence / ABM

ProvisioningNot Supported
Manual Cost$11,754/yr

6sense, the B2B revenue intelligence platform, has paused SCIM provisioning for new customers until Q4 2026. While existing customers with SCIM enabled can continue using it, new implementations are limited to JIT (Just-In-Time) provisioning through SAML SSO. This creates a significant gap for IT teams managing revenue intelligence access, as JIT only creates users on first login and provides minimal attribute mapping (email, first name, last name only). For an enterprise platform with typical pricing of $55,000-$130,000 annually, the absence of automated user lifecycle management is a substantial limitation. The lack of SCIM until Q4 2026 forces IT teams into manual provisioning workflows for a platform handling sensitive revenue data. While SAML SSO handles authentication, it doesn't address user lifecycle events like role changes, department transfers, or offboarding. This creates compliance risks in revenue teams where access to prospect data and sales intelligence must be tightly controlled. The nearly two-year wait for SCIM restoration means organizations implementing 6sense today face manual user management for the foreseeable future.

ActiveCampaign

No SCIM

Marketing Automation / Email

ProvisioningNot Supported
Manual Cost$11,754/yr

ActiveCampaign, the marketing automation platform, does not offer native SCIM provisioning on any plan. While the Enterprise plan ($145+/month) includes SAML 2.0 SSO with just-in-time (JIT) provisioning, this only creates user accounts on first login—there's no automated deprovisioning when employees leave or change roles. New SSO users are automatically added to a generic "SSO Users" group with configurable permissions, but IT teams have no way to programmatically manage user lifecycles or enforce granular access controls based on department or role changes. This creates a significant gap for marketing teams that need to manage access to customer data and campaign tools. When employees leave the company or change departments, their ActiveCampaign access must be manually revoked, creating compliance risks and potential data exposure. The lack of automated deprovisioning means former employees could theoretically retain access to sensitive marketing data and customer information until someone manually removes them from the platform.
