Certificate Switch 



 

Instructions on how to replace your server certificate


On October 16th 9:00 am CET we will replace the current server certificate which is used for the validation of the SOAP responses.

This time, we will replace it with a self-signed certificate which will be valid for five years. So we will no longer use the SSL certificate (for the webservices url) also for signing.

To continue to validate the responses you will need to take action. On this page your will find three ways to replace the server certificate in the case of different implementations.

Customers using the Java toolkit 

1. You can download the new toolkit here

2. Replace the java toolkit (jar) with the new one.

3. You can replace it at any time prior to October 16th, the toolkit will handle the switch automatically.

Customers using the .NET toolkit

The certificate needs to be updated at same time we update it on our side, and it requires new settings to handle the self signed certificate:

1. Download the new .NET toolkit with new settings here
 
2. You can replace the .NET toolkit any time before October 16th.

3. Backup the current *.acceptemail.com certificate from the certificate store: Manage Computer Certificates, Local Computer / Personal / Certificates)

4. On October 16th, 09:00 delete the current *.acceptemail.com certificate from Certificates – Local Computer and import the one from the toolkit in the “Certs” directory: Production-AcceptEmail-SOAP-signing-2025_Public.cer

Customers using their own or a third party implementation 

See if your own or third party implementation has the option to switch off response validation. If so: 

1. Modify your configuration to switch off response validation 

2. Download the new certificate here

3. Replace the existing certificate with the new one. 

4. After the certificate has been replaced on October 16th 2025 9:00 AM CET you can switch back on response validation

How you can install and replace the certificate depends on your method of implementation and the language used. 

If you do not have the option to temporarily switch off response validation, you will have to switch the certificate at the exact same time we switch it at our side. 

If you require assistance with replacing the certificate, feel free to contact support.
