Feature Release: Adobe Acrobat Sign – March 17^th Release Completed

The release was completed to all shards with no downtime to any services.

[Important - Updated] Changes to the Adobe Acrobat Sign Network Infrastructure have been scheduled for February 24- March 11, 2025 deployment

First Reported: September 2024 - Updated February 2025	Current Bookmark this notice

To improve Adobe Acrobat Sign service security and robustness, we will start to roll out network changes to include a web application firewall (WAF) in February 2025. These changes will route traffic into Acrobat Sign application servers through the WAF service. This routing will be invisible to most customers. Usage will not interfere with access to Acrobat Sign from any Adobe clients or integrations.

Action Required

None.
This change will not affect customer integrations, as the Acrobat Sign API and API domain names will not change. This solution is backward compatible with the published IP ranges.
Customers who have updated their security devices don't need to revert or make any other changes.

The current update schedule is:

Production Sandbox updates February 24, 2025.
Production shards: IN1, JP1, AU1, and SG1 will update March 3, 2025.
Production shards: NA2, NA3, and EU2 will update March 6, 2025.
Production shards: NA1, NA4, and EU1 will update March 11, 2025.

Ingress and Egress Access to Acrobat Sign

Acrobat Sign is no longer retiring the list of server ingress IP addresses as previously announced.
The server ingress and egress IP addresses, as documented on the System Requirements for Acrobat Sign page, will remain viable.
Why is Acrobat Sign making these Changes?

The use of a WAF improves Acrobat Sign's protection against harmful traffic and helps us better address security, robustness, and compliance requirements.
I have a custom integration into Acrobat Sign. Will my application be affected?

No, we don't expect any integrations to be negatively impacted.
Are there new IP address lists that can be substituted?

No.
The information on the System Requirements for Acrobat Sign page remains accurate.
My organization has implemented network filtering using Acrobat Sign's published domain list for traffic from our corporate network. Are we affected?

No.
The network changes described here do not impact Acrobat Sign's domain list, as documented on the System Requirements for Acrobat Sign page. Domain-level filtering is unaffected.
My organization employs IP address validation for email delivery from Acrobat Sign servers. Are we affected?

No.
The IP ranges for outbound mail relays, as listed on the System Requirements for Acrobat Sign page, are not changing.
My organization has configured our Acrobat Sign account to restrict access to our own IP addresses. Are we affected?

No.
Acrobat Sign can be configured to validate incoming traffic against customer-chosen IP addresses, as described on the Restrict access to your account using IP address ranges page. Such usage will not be affected by this change.
My organization has implemented network filtering using Acrobat Sign's published list of ingress IP addresses. Are we affected?

No.

The new WAF configuration is backward compatible with the existing network architecture, so no additional tuning of your security devices should be required.

Примечание.

Note that this refers to IP-level filtering for the environment hosting your application. Domain-level filtering is not affected.
I'm using the Salesforce integration with explicitly configured IP allow-listing. Do I need to do anything?

No.

The WAF installation requires no changes for existing Salesforce installations at this time.
The existing configuration/process, as described in the help documentation, remains the same, and administrators should follow all IP allow-listing steps.

ISV and Embed Partners should contact their Success Manager for any further questions.

[New] REST API GET /agreements Optimizations

First Reported: March 2025	Current Bookmark this notice

Adobe has optimized the implementation of the GET /agreements API to reduce the response time of the API calls. Internal testing indicates a reduction in response time up to an order of magnitude.

This optimization reduces the maximum number of agreements returned in a single call by lowering the maximum page size (the number of agreement records posted to the page). This maximum size is currently 500. (Adobe reserves the right to adjust this value in future releases.) Clients can request the number of agreements to be returned in a single call but will get back as many agreements as the service can provide. The actual number of agreements returned and a link to the next page of agreements are returned along with the agreements themselves.

There may be a small delay between creating an agreement and returning it in the GET /agreements API. In practice, this delay is rarely noticeable, and a subsequent call to the API would return the new agreement.

Available environments: Commercial, Government | Available tiers of service: Acrobat Sign Services, Government | Configuration scope: Enabled by default; Not configurable

[New] Adobe Acrobat Sign: Improved user onboarding.

First Reported: March 2025	Current Bookmark this notice

Deprecation of the Adobe Acrobat Sign REST API v1-v4.
End of support and removal of legacy REST API versions on December 1, 2025.

First Reported: September 2024	Current Bookmark this notice

Action Required

All customers using the API must update their APIs to utilize the version 6 endpoints as soon as possible to ensure uninterrupted availability.

Versions 1 through 4 of the Acrobat Sign REST API have been deprecated and will be removed from service on December 1, 2025.

Updating APIs can involve considerable effort, so all customers are strongly encouraged to scope and budget their update as soon as possible so that support can be fully engaged to resolve any questions or problems that arise before the December 2025 cutoff date.

While REST API v1-4 are deprecated, they will continue to function, and your applications will continue to work until December 1, 2025, when the REST API v1-4 will be removed.

After December 1, 2025, applications built on the REST API v1-4 will cease functioning.

Classic reporting to be removed from service in the first half of 2025

First Reported: September 2022 - Updated March 2024	Current Bookmark this notice

Classic reporting will be completely removed from the Acrobat Sign interface in the first half of 2025. This includes the switch link that allows changing between environments. Once removed, customers will not be able to return to the classic environment to review classic reports, and scheduled reports will stop executing.

The modern reporting environment will remain as the only reporting solution.

All customers are strongly encouraged to recreate all of their existing reports in the new environment as soon as possible.

External source drives to be removed from support in the new Request Signature experience

First Reported: May 2024	Current Bookmark this notice

The option to use an external drive for uploading files will be limited to OneDrive only in the new Request Signature experience.

It's recommended that customers who use other options for file upload use the vendor-specific application to provide a networked drive that can be accessed through the native file picker on the user's local system.

Adobe Acrobat Sign SSL Certificate updates in January, 2025

First Reported: December 2024	Removed from Current list: February 2025 Bookmark this notice

Adobe Acrobat Sign will rotate the Adobe Acrobat Sign SSL Certificate on January 22, 2025.

In addition, a new SSL certificate is being deployed to support the WAF network changes being made in January 2025. This new certificate directly impacts access to the Acrobat Sign service and must be installed before the WAF goes online.

Action Required

Every customer account that explicitly secures network activity must include the new WAF SSL certificate in its list of stored certificates.
If you have custom-built integrations with Acrobat Sign using either the SOAP or REST APIs and if any of these integrations have ‘pinned’ the existing public key, no other action is required.
If you are using Acrobat Sign’s SSL certificates for SSO, or if you’re pinning the certificate itself (or using other methods), you can find the new Acrobat Sign SSL certificates in the Adobe Acrobat Sign System Requirements.
- If your SSO configuration supports multiple public certs/chains, you can add the new certificates now and remove the old public cert/chain from your configuration after the January switch.
- If your SSO does not support multiple public certs/chains, you will need to sync your SSL switch with Acrobat Sign on January 22, 2025.

The new SSL certificates will be active on January 22, 2025.

Custom Workflow Designer places a 100-character limit on labels for all new and existing workflow templates

First Reported: November 2024	Removed from Current list: January 2025 Bookmark this notice

With the November 2024 release, the editable labels in the Custom Workflow Designer have been limited to 100 characters. This limit is evaluated when the workflow is created or updated.

Preexisting workflows that have labels over 100 characters can still be sent successfully, but if the workflow is updated, the label must be reduced to 100 characters or less before it can be saved. Offending labels are outlined in red for easy discovery.

New workflows will warn about the label limit before they are saved.

Action Required

It is recommended that admins with control over custom workflows open and review each workflow to ensure that they don't have errors on their template.
