+
+# scaleway_lb_certificate
+
+Get information about Scaleway Load-Balancer Certificates.
+
+This data source can prove useful when a module accepts an LB Certificate as an input variable and needs to, for example, determine the security of a certificate for your LB Frontend associated with your domain, etc.
+
+For more information, see [the documentation](https://developers.scaleway.com/en/products/lb/zoned_api/#certificate-330754).
+
+## Examples
+
+### Let's Encrypt
+
+```hcl
+resource scaleway_lb_ip main {
+}
+
+resource scaleway_lb main {
+    ip_id = scaleway_lb_ip.main.id
+    name = "data-test-lb-cert"
+    type = "LB-S"
+}
+
+resource scaleway_lb_certificate main {
+    lb_id = scaleway_lb.main.id
+    name = "data-test-lb-cert"
+    letsencrypt {
+        common_name = "${replace(scaleway_lb.main.ip_address, ".", "-")}.lb.${scaleway_lb.main.region}.scw.cloud"
+    }
+}
+
+data "scaleway_lb_certificate" "byID" {
+    certificate_id = "${scaleway_lb_certificate.main.id}"
+}
+
+data "scaleway_lb_certificate" "byName" {
+    name = "${scaleway_lb_certificate.main.name}"
+    lb_id = "${scaleway_lb.main.id}"
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+- `certificate_id` - (Optional) The certificate id.
+    - Only one of `name` and `certificate_id` should be specified.
+
+- `name` - (Optional) The name of the certificate backend.
+    - When using a certificate `name` you should specify the `lb-id`
+
+- `lb_id` - (Required) The load-balancer ID this certificate is attached to.
+
+## Attributes Reference
+
+See the [LB Certificate Resource](../resources/lb_certificate.md) for details on the returned attributes - they are identical.
