Using the SDK

Simply import the SDK and provide the API credentials provided to you. They may be an API Token or OAuth 2.0 Credentials. Examples are listed below for each feature.

Customer Management

Our Customer Management service provides administrative operations to manage Customer accounts and Customer User accounts for a Partner. These operations allow a partner to automate administrative tasks on their customers and customer user accounts.

To use this Customer Management service, use the API Token provided to you.

Customer

Customer Account Management Operations allows management of customer accounts

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/customer"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	customerService, err := customer.New(sdkConfig)
	newCustomer := customer.Customer{
		// ...
	}
	addParams := customer.NewAddCustomerParams()
	addParams.Customer = newCustomer
	resp, err := customerService.AddCustomer(*addParams)
	// ...
}

Customer User

Customer User Account Management Operations allows you to manage user accounts under a (parent) customer.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/customer"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	customerService, err := customer.New(sdkConfig)
	customerUser := customer.CustomerUser{
		// ...
	}
	addParams := customer.NewAddCustomerUserParams()
	addParams.CustomerUser = customerUser
	// ...
	resp, err := customerService.AddCustomerUser(*addParams)
	// ...
}

Edge CNAME

Our User-Friendly URL, also known as Edge CNAME, takes advantage of an Edge CNAME configuration and a CNAME record to provide a friendlier alternative to a CDN URL. An edge CNAME URL is specific to the platform from which it was configured.

For more information, please read the official documentation for Edge CNAME

To use the edge CNAME service, use the API Token provided to you.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/edgecname"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	edgecnameService, err := edgecname.New(sdkConfig)
	cname := edgecname.EdgeCname{
		// ...
	}
	addParams := edgecname.NewAddEdgeCnameParams()
	addParams.EdgeCname = cname
	// ...
	resp, err := edgecnameService.AddEdgeCname(*addParams)
// ...
}

Customer Origin

Our Customer Origin Service allows you to serve content stored or generated by third-party web servers (e.g., web hosting) via the CDN by:

• Creating a customer origin configuration. This type of configuration maps one or more servers to a CDN URL.
• (Optional) Creating an edge CNAME configuration that allows you to serve traffic via the CDN without having to update your links. This type of configuration maps a customer origin configuration to a CNAME record.

For more information, please read the official documentation for Customer Origin

To use the Customer Origins service, use the API Token provided to you.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/edgecname"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	originService, err := origin.New(sdkConfig)
	newOrigin := origin.Origin{
		// ...
	}
	addParams := origin.NewAddOriginParams()
	// ...
	addParams.Origin = newOrigin
	resp, err := originService.AddOrigin(*addParams)
// ...
}

Route (DNS) - BETA

Our Route (DNS) solution is a reliable, high performance, and secure DNS service that provides capabilities such as:

• Load balance traffic for a CNAME record or a subdomain for a primary zone hosted on another DNS system.
• Establish a failover system for a CNAME record or a subdomain for a primary zone hosted on another DNS system.
• Create a standard DNS zone. Optionally, load balance or failover requests to that zone.
• Import a secondary DNS zone by creating a master server group and a secondary zone group.
• Verify a server's capability to fulfill requests through health checks performed from around the world.

For more information, please read the official documentation for Route (DNS)

To use the Route(DNS) service, use the API Token provided to you.

Master Server Group

A master server group allows quick and easy management of master name servers, while a secondary zone group defines the secondary zones that will be imported from servers defined in a master server group and any TSIG keys that should be used for the zone transfer.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/routedns"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	routeDNSService, err := routedns.New(sdkConfig)
	masterServerGroup := buildMasterServerGroup()
	addParams := routedns.NewAddMasterServerGroupParams()
	addParams.MasterServerGroup = masterServerGroup
	// ...
	resp, err := routeDNSService.AddMasterServerGroup(*addParams)
// ...
}

Real Time Log Delivery (RTLD)

Our Real-Time Log Delivery (RTLD) service delivers log data in near real-time to a variety of destinations.

For more information, please read the official documentation for Real-Time Log Delivery (RTLD).

To use the Rules Engine service, use OAuth 2.0 Credentials.

Real-Time Log Delivery Rate Limiting (RTLD Rate Limiting)

Delivers log data that describes requests for which Web Application Firewall (WAF) enforced a rate limit as defined through a rate rule.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/waf"
)
// ...
	idsCredentials := edgecast.IDSCredentials{
		ClientID:     clientID,
		ClientSecret: clientSecret,
		Scope:        scope,
	}
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.IDSCredentials = idsCredentials
	rtldService, err := rtld.New(sdkConfig)
	addParams := profiles_rl.NewProfilesRateLimitingAddCustomerSettingParams()
	addParams.SettingDto = &rtldmodels.RateLimitingProfileDto{
		// ...
	}
	addResp, err :=
		rtldService.ProfilesRl.ProfilesRateLimitingAddCustomerSetting(addParams)
// ...
}

Rules Engine

Our Rules Engine allows the customization of requests handled by our CDN. Sample customizations that may be performed are:

Override or define a custom cache policy Secure or deny requests for sensitive content Redirect requests to a different URL

For more information, please read the official documentation for Custom Request Handling via Rules Engine.

To use the Rules Engine service, use OAuth 2.0 Credentials. A Policy should be constructed as a JSON object passed as a string.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/waf"
)
// ...
	policyString := `{
		// ...
	}`
	idsCredentials := edgecast.IDSCredentials{
		ClientID:     clientID,
		ClientSecret: clientSecret,
		Scope:        scope,
	}
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.IDSCredentials = idsCredentials
	rulesengineService, err := rulesengine.New(sdkConfig)
	addParams := rulesengine.NewAddPolicyParams()
	addParams.PolicyAsString = policyString
	addPolicyResp, err := rulesengineService.AddPolicy(*addParams)
// ...
}

Web Application Firewall (WAF)

Our WAF service provides a layer of security between many security threats and your external web infrastructure. WAF increases security by monitoring, detecting, and preventing application layer attacks. It inspects inbound HTTP/HTTPS traffic against reactive and proactive security policies and blocks malicious activity in-band and on a real-time basis.

For more information, please read the official documentation for Web Application Firewall (WAF).

To use the WAF service, use the API Token provided to you.

Access Rules

An access rule identifies legitimate traffic and threats by ASN, Cookie, Country, IP Address, Referrer, URL, User agent, HTTP method, Media type, File extension, and Request headers.

import (
	"github.com/EdgeCast/ec-sdk-go/edgecast"
	"github.com/EdgeCast/ec-sdk-go/edgecast/waf"
)
// ...
	sdkConfig := edgecast.NewSDKConfig()
	sdkConfig.APIToken = "MY API TOKEN"
	wafService, err := waf.New(sdkConfig)
	rule := waf.AccessRule{
		// ... 
	}
	resp, err := wafService.AddAccessRule(rule)
// ...
}
