@anonbumqams Thanks for reaching out. For custom payload, at present we only support Email methods.
Important things to consider while designing a custom payload is that Certain trademarks, logos, symbols, insignias and other source identifiers receive heighted protection under local, state and federal statutes and laws. Unauthorized use of such indicators can subject the users to penalties, including criminal fines.
Though not an extensive list, this includes the Presidential, Vice Presidential, and Congressional seals, the CIA, the FBI, Social Security, Medicare and Medicaid, the United States Internal Revenue Service, and the Olympics. Beyond these categories of trademarks, use and modification of any third-party trademark carries an inherent amount of risk.
Using your own trademarks and logos in a payload would be less risky, particularly where your organization permits the use. If you have any further questions about what is or is not appropriate to use when creating or configuring a payload, you should consult with your legal advisors.
