Especially with integration platforms such as the SAP Integration Suite, new requirements arise in terms of security, controllability and scalability. <\/p>\n<p>Internal and external partners must be integrated into integration processes in a partner-specific, secure and traceable manner. Without a clearly defined concept for partner data management, the connection can quickly become complex and time-consuming. <\/p>\n<p>As part of the <strong>InnovateSAP<\/strong> initiative, we support companies in developing suitable best-practice concepts for secure and efficient partner integration.<\/p>\n<h3><strong>Starting situation<\/strong><\/h3>\n<p>Many companies currently do not have a central, partner-specific concept for connecting internal and external partners to their integration platform.<\/p>\n<p>This creates several challenges during operation:<\/p>\n<ul>\n<li>High effort in <strong>connecting new partners<\/strong><\/li>\n<li>Complex <strong>care and maintenance of existing connections<\/strong><\/li>\n<li><strong>Lack of central controllability of access<\/strong><\/li>\n<li>Potential <strong>security risks<\/strong><\/li>\n<\/ul>\n<p>A structured concept for partner connection via <strong>SOAP, HTTP or OData interfaces<\/strong> is therefore becoming a central success factor for a stable and secure integration architecture.<\/p>\n<h3><strong>Approach<\/strong><\/h3>\n<p><a href=\"https:\/\/www.ho2-gmbh.de\/wp-content\/uploads\/2026\/03\/Konzepte_Ubersicht.avif\"><img data-dominant-color=\"95b1c4\" data-has-transparency=\"false\" style=\"--dominant-color: #95b1c4;\" decoding=\"async\" class=\"alignnone size-full wp-image-7473 not-transparent\" src=\"https:\/\/www.ho2-gmbh.de\/wp-content\/uploads\/2026\/03\/Konzepte_Ubersicht.avif\" alt=\"\" width=\"1548\" height=\"548\" data-wp-pid=\"7473\" data-pin-nopin=\"nopin\" srcset=\"https:\/\/www.ho2-gmbh.de\/wp-content\/uploads\/2026\/03\/Konzepte_Ubersicht.avif 1548w, https:\/\/www.ho2-gmbh.de\/wp-content\/uploads\/2026\/03\/Konzepte_Ubersicht-640x227.avif 640w, https:\/\/www.ho2-gmbh.de\/wp-content\/uploads\/2026\/03\/Konzepte_Ubersicht-768x272.avif 768w\" sizes=\"(max-width: 1548px) 100vw, 1548px\" \/><\/a>Several architectural concepts are available for the secure and efficient connection of internal and external partners. These differ in terms of security level, scalability and administration effort. <\/p>\n<p>Depending on the requirements and number of partners, three established concepts can be used:<\/p>\n<p><strong>Concept I \u2013 Role-based BTP Service Keys<\/strong><\/p>\n<p>Partners are connected via <strong>service instances and service keys<\/strong> within the SAP Business Technology Platform. Access is role-based and can be accessed via various authentication mechanisms: <\/p>\n<ul>\n<li>Basic Authentication<\/li>\n<li>OAuth<\/li>\n<li>Certificates<\/li>\n<\/ul>\n<p>Integration via an identity provider is also possible, for example via SAP Cloud Identity Services or external identity providers such as Microsoft Azure Active Directory.<\/p>\n<p>For an increased level of security, it is recommended to use <strong>OAuth or certificate authentication<\/strong> .<\/p>\n<p><strong>Concept II \u2013 Certificate-based partner connection<\/strong><\/p>\n<p>In this approach, authentication is carried out via <strong>client certificates<\/strong>, which achieves a particularly high level of security.<\/p>\n<p>Typical features:<\/p>\n<ul>\n<li>Partner-specific integration flows<\/li>\n<li>Clear separation of partner access<\/li>\n<li>High traceability and auditability<\/li>\n<\/ul>\n<p>This concept is particularly suitable for companies with <strong>regulatory requirements or particularly sensitive data<\/strong>.<\/p>\n<p><strong>Concept III \u2013 SAP API Management<\/strong><\/p>\n<p>SAP API Management can be used to build a flexible and scalable partner ecosystem.<\/p>\n<p>Various security mechanisms are available:<\/p>\n<ul>\n<li>OAuth<\/li>\n<li>API Keys<\/li>\n<li>IP Filters<\/li>\n<li>Quotas and Spike Arrest<\/li>\n<li>Threat Protection<\/li>\n<\/ul>\n<p>By combining <strong>OAuth and API Keys<\/strong> , fine-grained access control can be implemented.<\/p>\n<p>All concepts also support secure connection to on-premise systems via the SAP Cloud Connector. This enables a secure tunnel between the on-premise landscape and the cloud integration platform. <\/p>\n<h3><strong>Steps of implementation<\/strong><\/h3>\n<p>The structured use of these concepts enables companies to systematically develop their partner integration and adapt it to your individual requirements.<\/p>\n<p><strong>Providing clarity<\/strong><\/p>\n<p>In the first step, the existing partner landscape is analyzed.
