Let's Encrypt
The Let’s Encrypt CA Connector enables CERTInext to integrate directly with Let’s Encrypt using the ACME (Automatic Certificate Management Environment) protocol for automated SSL/TLS certificate lifecycle management. Once configured, CERTInext can communicate securely with Let’s Encrypt services to automate certificate issuance, renewal, validation, and lifecycle tracking directly from the CERTInext platform.
This integration helps organizations simplify public SSL/TLS certificate management while leveraging Let’s Encrypt’s free and automated certificate services.
Typical use cases include:
Automated SSL/TLS certificate issuance
ACME-based certificate automation
Web server certificate management
Short-lived certificate renewals
Public website security automation
DevOps and cloud-native certificate provisioning
Accessing the Let’s Encrypt Connector
To configure a Let’s Encrypt connector:
Navigate to Integrations → CA Connectors → Let’s Encrypt
Click Create CA Connector
This opens the Let’s Encrypt connector configuration page where ACME connectivity and account details are configured.
Let’s Encrypt Connector Configuration Fields
The following fields are required when creating a Let’s Encrypt connector.

Name
Defines a unique name for the connector configuration.
Example:
This name is used internally within CERTInext to identify the integration.
ACME Environment
Specifies the Let’s Encrypt ACME environment to be used.
Available options include:
Production
Used for live certificate issuance from Let’s Encrypt’s production environment.
Certificates issued from this environment are publicly trusted and intended for real production workloads.
Staging
Used for testing and validation purposes.
The staging environment helps administrators validate automation workflows without hitting production rate limits. Certificates issued from staging are not publicly trusted.
It is recommended to use the Staging environment during initial configuration and testing.
Contact Email
Specifies the administrator or operational contact email address associated with the ACME account.
Example:
This email may be used by Let’s Encrypt for important notifications such as:
Expiry alerts
ACME account notices
Operational communications
Testing the Connector
After entering all required details:
Click Test Connection
CERTInext validates:
ACME endpoint connectivity
Let’s Encrypt environment access
Account registration capability
API communication availability
If the validation succeeds, the connector can be saved and used for certificate operations.
Certificate Operations Supported
Once configured, the Let’s Encrypt connector enables CERTInext to perform:
Automated certificate issuance
Domain validation workflows
ACME challenge handling
Certificate renewal
Certificate revocation
Lifecycle monitoring
Certificate inventory tracking
These operations are executed through secure ACME-based communication between CERTInext and Let’s Encrypt.
Domain Validation Support
The Let’s Encrypt connector supports automated domain validation using standard ACME validation methods, including:
DNS-based validation
HTTP-based validation
CERTInext can coordinate validation workflows using supported DNS connectors and automation capabilities.
Operational Flow
The typical certificate lifecycle workflow using the Let’s Encrypt connector is:
For automated environments, CERTInext can streamline the entire issuance and renewal lifecycle with minimal manual intervention.
