API polling threshold limit

First Reported: August 2025 - Updated February, 2026

Current 

Bookmark this notice

To help maintain system stability and improve performance, Adobe Acrobat Sign is introducing a polling threshold for GET API endpoints. This policy limits how frequently client applications can make identical API calls to the Acrobat Sign service.

High-frequency polling creates unnecessary load on backend systems, which can degrade performance and slow response times. API developers are encouraged to use webhooks for near real-time updates instead of repeated polling.

What’s changing

The polling policy applies to all GET API endpoints for identical calls.

A limit is applied to how often the same effective user can make the same API call to Acrobat Sign. An error is returned when the same effective user makes identical calls more frequently than the applicable polling threshold allows.

For example, a repeated request to the same endpoint for the same agreement or library document is treated as an identical call. Requests for different agreements or library documents are treated as distinct calls because each object represents a different request target.

Examples of affected endpoints

Status retrieval

  • GET /agreements/{agreementId} — Retrieves the current status of an agreement.
  • GET /agreements/{agreementId}/documents/{documentId} — Retrieves the file stream of a document within an agreement.

Listing, events, and library documents

  • GET /agreements — Retrieves agreements for the user.
  • GET /agreements/{agreementId}/events — Retrieves event information for an agreement.
  • GET /libraryDocuments — Retrieves library documents for the user.
  • GET /libraryDocuments/{libraryDocumentId} — Retrieves information for a specific library document.

Polling policy details

The Minimum Object Polling Interval (MOPI) defines how often the same effective user can make the same GET API request to the Acrobat Sign service.

The default MOPI varies by service tier:

  • GLOBAL, ENTERPRISE, and DEVELOPER tiers: Three identical calls per one-minute interval.
  • All other tiers: Three identical calls per three-minute interval.

If the same effective user makes identical GET requests more frequently than the tier allows, Acrobat Sign returns a 429 Too Many Requests response with a Retry-After header.

A request is considered identical when the same effective user makes the same GET request with the same request path and headers within the applicable polling interval.

ETag handling

Applications may continue to use ETags and the If-None-Match header for endpoints that support conditional GET requests.

For conditional GET requests that are allowed under the polling threshold, Acrobat Sign may return 304 Not Modified when the resource has not changed.

When the polling threshold is exceeded, Acrobat Sign returns 429 Too Many Requests with a Retry-After header, even when the request includes an If-None-Match header.

Action required

If your application requires near real-time updates, use webhooks instead of polling. Webhooks provide a more efficient and scalable way to receive timely updates.

If webhooks cannot be implemented, applications should use client-side caching to store and reuse API responses.

  • When a 304 Not Modified response is received, use the cached data instead of making another API call.
  • When a 429 Too Many Requests response is received, retry the API call only after the number of seconds provided in the Retry-After header.

Resources

Timeline

The updated MOPI thresholds are already in production.

  • The updated ETag throttling behavior is included in the 17.1.1 release. After this change, Acrobat Sign returns 429 Too Many Requests for throttled requests, including conditional GET requests that include an If-None-Match header.
  • The polling policy is set to ENFORCED for new accounts in the Sandbox environment on February 11, 2026.
  • The polling policy is set to ENFORCED for new accounts in the Production environment on April 5, 2026.

SSL/TLS certificate rotation updates: transition to shorter certificate validity periods underway

First Reported: March 2026

SSL/TLS Certificate Rotation Updates – Transition to Shorter Validity Periods 

The SSL/TLS industry is transitioning to significantly shorter certificate validity periods. This change is driven by updates from the CA/Browser Forum (the governing body for publicly trusted certificates) and is being adopted across major certificate authorities (CAs), including DigiCert. 

As a result, certificate lifetimes will gradually reduce from the current ~398 days to as short as 47 days over the next several years. 

What Is Changing? 

The maximum validity period for publicly trusted TLS certificates will be reduced to 47 days. This requirement is defined by the CA/Browser Forum and applies industry-wide. 

Why Is This Change Happening? 

Shorter certificate lifetimes improve security by: 

  • Reducing the exposure window if a certificate or private key is compromised 
  • Limiting reliance on certificate revocation mechanisms 
  • Encouraging automated certificate lifecycle management 
  • Improving overall internet security posture 

Major browser vendors (Google, Apple, Mozilla, Microsoft) support this transition. 

For additional industry context, see DigiCert’s announcement: 
TLS Certificate Lifetimes Will Officially Reduce to 47 Days 

How This Affects You 

  • Increased Certificate Rotation Frequency 
    • Certificates will rotate more frequently as maximum validity periods decrease.  
  • Automation Is Required 
    • Due to the shorter validity periods, certificate renewals are expected to be fully automated. Manual renewal processes are not sustainable at this frequency. 

If your environment depends on certificate pinning, manual trust stores, or static certificate references, review your configuration to ensure compatibility with frequent renewals. 

Customer Notifications 

Previously, notifications were sent when certificates rotated on an annual basis. 

Effective at the end of June 2026, routine notifications for standard certificate rotations will be discontinued. 

With shorter validity periods and automated renewals: 

  • Routine certificate rotations will not generate customer notifications. 
  • Notifications will be sent only in cases of: 
  • Renewal failures 
  • Service impact 
  • Customer action required 

This approach aligns with industry best practices for automated certificate lifecycle management. 

No Action Required (If Automation Is Enabled) 

If your integration relies on standard TLS trust validation and does not depend on certificate pinning, no action is required. 

Certificates will continue to renew automatically before expiration. 

When Action May Be Required 

You may need to take action if: 

  • You use certificate pinning (SPKI or full certificate pinning) 
  • You maintain manual certificate stores 
  • You have firewall rules tied to specific certificate fingerprints 
  • You operate systems that do not support automated certificate updates 

If unsure, consult your security or infrastructure team. 

Frequently Asked Questions 

  • Is this an Adobe-specific change? 
    • No. This is an industry-wide change mandated by the CA/Browser Forum and implemented by all major certificate authorities. 
  • Will service availability be affected? 
    • No. Certificates will renew automatically prior to expiration. There is no expected downtime as part of normal rotation. 
  • When will certificate rotation notifications stop? 
    • Routine certificate rotation notifications will stop at the end of June 2026. Customers will continue to be notified only if action is required or if an issue impacts service. 
  • Where can I learn more?

Persistent Informational Notifications


SMS delivery is blocked in Thailand

First Reported: February 2026

Current 

Bookmark this notice

Summary
Due to updated regulatory requirements in Thailand, Agreement Delivery via SMS is currently not supported for recipients with Thai phone numbers.

What’s changing
Thailand has introduced updated regulations that restrict SMS messages containing URLs from directing recipients to flows that require user interaction. Because signing an agreement requires recipient interaction, SMS delivery for this use case is restricted.

Who is affected

  • Agreements sent using Agreement Delivery via SMS.
  • Recipients with Thai (+66) phone numbers.

Impact
Recipients with Thai phone numbers may not receive SMS messages containing agreement links. As a result, recipients may be unable to access and complete the signing process when SMS delivery is used.

This limitation is regulatory in nature and is not caused by a service outage or product defect.

Timing
There is currently no confirmed timeline for when this restriction may be lifted or a technical solution will be applied. This notice will be updated when conditions change.

Required actions

  • Do not use Agreement Delivery via SMS for recipients with Thai phone numbers.
  • Include email as an alternative delivery method to ensure agreement delivery.

Additional details
This limitation applies only to SMS-based delivery. Other agreement delivery and authentication methods are not affected.
